Video extenders enable you to extend video between the source and the output devices over long distances. These devices use standard Cat5 / Cat5e / Cat6 UTP cables to send video between the local transmitting unit and the remote receiving unit. Since these Video type use Cat5/Cat6 cables thus eliminating the need for long bulky VGA cables. These Cat5 Extender units transmit Video locally as well as remotely to one or multiple screens.

Amongst the various types of these units, the most common is the VGA Extender. These extenders are available with 1/2/4/8 ports and with optional stereo audio or RS232 control. These are easy to install and support simple plug and play functionality. These Cat5 Extender units provide sharp and clear images with resolutions of up to 1900 x 1200. They provide equalization and video signal gain adjustment. While VGA extenders are the most popular, video extenders are also available in other formats as well, including, DVI extender, HDMI extender, Composite extender, and Component extender.

KVM Extender allows the keyboard, mouse and monitor to be placed up to 1000 feet away from a computer. They transmit data and high-resolution video up to 1280 x 1024 @ 60Hz. These Cat5 extenders are compatible with DOS, Windows (3x, 9x, 2000, NT, ME, XP), Novel, Linux, UNIX, HP UNIX, QNX, SGI, FreeBSD, BeOS and Open VMS.

Spyware is malicious software (malware) that installs itself or runs on your computer without providing you with adequate notice, consent or control. It can monitor your online behaviour or collect your sensitive personal information such as personally identifiable information and passwords. It could as well display annoying pop-up advertisements, change your computer settings or cause your computer to run slowly. Because spyware does not obtain your consent before installing or running on your computer, and may not immediately display any noticeable symptoms after it infects your computer, you might not actually be aware of its presence in your PC.
 
Spyware and other malware are most commonly installed through free software downloads, such as file sharing, screen savers and search toolbars. Also, they could be installed by websites, downloaded programs, or software you might install from a CD, DVD, external hard disk, or other removable media. Some spyware can be installed from a website through an embedded script, or program in a webpage while some potentially unwanted software require your help to install through web pop-ups or free software that requires you to accept a downloadable file. In other words, you can get spyware installed in your computer without knowing it.
 
Let us take a look at the signs you should look out for to know if your computer has been infected by spyware or other malware:

1.    If you notice new toolbars, links, favourites or bookmarked web pages, which you did not intentionally add to your web browser, you should know that spyware has sneaked into your computer.
2.    When your default homepage, mouse pointer or search program changes without your intervention, it indicates the presence of spyware.
3.    If you typed the URL for a specific website (for instance, a search engine), but you are redirected to another web site without notice, is a typical action of potentially unwanted software.
4.    If pop-up advertisements are constantly displayed on your screen, even when you are not currently working on the internet, your spyware alarm should be set off.
5.    Spyware may also cause your computer to suddenly start to run very slowly.
 
It is possible to not have any of these symptoms but yet, your computer might still be infected by spyware. You are therefore expected to take proactive steps to keep this form of malware at bay. By diligently taking the actions below, you are ensuring that you protect your computer from spyware infection:

 Run Up to Date Anti-Spyware Software – anti spyware software helps prevent malicious software, spyware, and other potentially unwanted software or adware from installing itself or running on your computer. Antispyware program can also perform a computer scan to locate and automatically remove malware that might already be installed on your PC.

Windows Defender is a version of anti-malware software that is shipped together with windows operating system but there are other sources of anti spyware software including those which are customizable to handle all forms of malicious software.

 Keep Your Computer Up to Date – always update the security features of your computer. To do this automatically, you need to turn your windows automatic updater on at all times. Similarly, you must visit your anti-spyware software publisher’s website often to check for and download updates of your software, to your computer.

 Review License Agreements Before Installing Software – before you download any free software such as file sharing programs or screen savers, please read the license agreement carefully. Do not automatically agree to download any software offered by any website; rather look out for clauses where you might be required to accept advertisements and pop-ups from the company. In some instances, the software publisher may require you to agree that the program will send certain kinds of information back to them. In such cases, if you do not trust the website, refuse to download such software to avoid installing spyware in your computer.

 When Pop-Up Won’t Close Except You Take An Action – sometimes a website could repeatedly display pop-ups asking you to install a toolbar, change your home page or take other similar action. The first action to take on such a situation is to try to close the pop-up browser window, if the pop-up still appears, right-click the internet explorer button in the task bar at the bottom of your screen and then click close group. If every effort to close the pop-up window fails, as a last resort, close any other program you have open and restart your computer. 
No effort should be spared in getting rid of spyware because of the enormous threat it poses to the health and efficiency of your PC and your online safety. I strongly recommend that you follow these simple steps diligently to achieve the desired results.

How long have you own your computer? 1 month? 1 year or many years? Regardless how long you own your computer, it is extremely important to have a very good backup system. I’m sure all of us got many collections of files and folders stored in the computer’s hard drive. Some of us may have thousands of songs and movies (illegally not to mention but who doesn’t :p) downloaded from numerous sources on the net and full archive of photos from 5 to 15 years ago. Have you ever imagined if someday your hard drive crashed or fried by overheating or stolen (happened to a famous movie director)? What will you do? You might try to recover your drive but the success is not guaranteed though (if you got 50% recovery you’re lucky enough). But what if you’re out of luck? You gonna lose all of your data! All of your collection of files will be gone. Whatever you have on your hard drive I’m sure you can’t afford to lose them. That’s why everyone must have a good backup system.

How are backups being done?

Backup is simply means having the extra copy of files stored inside the computer’s hard drive elsewhere. There are few ways of how backup can be done. The simplest way of doing backup is having an external hard drive when you can store all of your data in it. You can also upload them to online file hosting services or having your multiple drives at RAID 1 configuration (may require advance knowledge on computing so it won’t be discussed here).

1) Online file hosting.

Online file hosting means hosting or keeping files online. Keeping files on the net doesn’t necessarily mean it is freely available for every internet user. You can save your files privately or share them with anyone who has the access to the internet. There are tons of online file hosting services freely available to use. I’m sure you’ve heard about RapidShahre, SaveFile or BoxNet. These are a few example of site that offers free online file hosting while at the same time also offering file sharing. I’ve personally use some but Orbitfiles is the only one I’m sticking with until now. It offers 6 Gigabytes of storage for free. Orbitfiles users can also share or even sell them (assuming you have full rights on ‘em)! To host your files online, you will need to upload them to the server.

Most of the services use internet interface to upload file like you do when uploading photos and videos to Blogger or WordPress. Some of them also provide free application software for easy uploading process. Orbitfiles users can download free software called Hercules uploader which is very handy to upload your files to the server. You can schedule the uploading process to be at 3:00 am every morning or 2:00 pm every Monday. It is free and easy to use. I use online file hosting only for important and small files. Small files are much faster to upload than larger files. If you need security for your files, you can password protect your files using Winrar. A simple .zip or .rar file with a strong encryption (password) is almost impossible to be opened without the correct password. Even with a good computer, you’ll need years to break the code using bruteforce attack. You can click the link below to visit Orbitfiles website.

2) External Hard Drives

The easiest way to do backup is by having an external hard drive. External hard drives have become the most popular option for either extra storage space or backup purposes. Year by year the price of hard drive dropped quite rapidly. External hard drives come with a wide range of capacity from old 8 Gigabytes to 2 Terabytes (1 Terabytes = 1000 Gigabytes). 2TB had drives are still expensive at the moment. An external with descent capacity (160GB – 500GB) is just nice for backup purposes. They are not that expensive as 2TB. Once you have one, you can start backing up your files. However to do it in regular basis is quite boring and after some times you won’t care about you backup anymore. Some external hard drives come with its own backup software which is doing the boring part for you. I have one Seagate hard drive that comes with a program call drive manager where you can set the files or folders to be backed up automatically at any time 7 days a week. If the program detects any change of files in your selected folder, it will update your backup folder on external hard drive on the next scheduled time. You can also disable auto backup if you prefer that way. Remember this, computers and hardware can be insured, but the only insurance for data is backup!

Trojan, in the context of computing and software, is also called Trojan horse. It is a class of computer threats that appears to be performing a desirable function, but in fact the function performed is malicious and this function allows unauthorized access to the host machine. It also gives them a file saving capability even without the user’s consent and also control of the computer. You download them unwillingly through such programs as computer games, which leave a door open when executed after payment by Trojan developers to do so. Trojan enters through these doors and the example of a notorious Trojan is waterfalls.scr which is disguised as a screen saver.

Trojans are classified according to their method of breach to computers and they include those that remotely access your PC, those that destroy your data, those that use denial-of-attack, software that disables security and finally those that are downloaded into the PC in the normal manner.

To prevent protection, you must always be careful about the programs you download and you should avoid those whose source and contents you are not sure about and to avoid such files even when they are from friends. You should always be on the lookout for hidden file extensions to keep off those that might be Trojan and you should avoid features that automatically get or preview files.

You should not be reckless just because you have an updated anti virus because some Trojans have the ability of blind siding anti virus programs. There are also Anti-Trojan programs that are dedicated to these infections and you can also get rid of them through IRC Help Channels. Please visit http://www.spywareandadwareremovalsoftware.org.

So your home page has changed and you can’t change it back? If you answered yes then NOW is the time to ACT. Visit this website and get your Free Spyware Scan. Do NOT leave your computer infected with spyware, adware, or malware.

I need to first say that you need Updates turned on and you should have at least XP Service pack two installed. This fixes a large amount of security flaws and recognizes more current technology. This does not apply Vista. When you select an option under Automatic updates you should pick “Notify me but don’t automatically download or install them”. Although the updates are supposed to help protect you, they can also cause problems. This will let you know what is going on and will give you the control you need. Never turn them off.

Service pack3 for XP is a good sample. Mostly XP never ran as good as when they gave us this service pack. However, I have seen times when it caused problems. The situations I have seen are: system freezes, Can not send or receive email and web page will not load. There may be others but this is what I ran into. The solution is to uninstall it if it is already installed. Just go to add/remove programs and remove it. You should reboot your computer to be sure every thing is good. In the event that doesn’t solve your problem the registry may be corrupt or you may have a Virus or spyware.

Explorer 8 can be another problem. If you are currently running any version of XP I do not recommend that you upgrade to this version. Stick with Explorer 7 when you’re running XP or at least give it some time so that “bugs” can be worked out. I have seen it run ok on Vista so far.

If you are having trouble loading Internet Explore you can try Firefox. The trick is that you must already have it installed “before” the problem occurs. Open it if you have it. If it works then you know that your other browser and/or registry are corrupt.

Another “possible” solution is to use system restore. If you are using XP go to start > all programs > accessories > system tools and click on system restore. Why? Because this will take you back to a date that is before the day the change occurred. Vista has system restore also but the location is different.

If system restore doesn’t work you may need to reload the operating system. If you do that you need to back up all files that you ever want to see again. You also need to verify that you have all the programs you need.

Be careful!! When you allow an update or install anything be sure it is from a reliable source. System updates should be coming from Microsoft “only”. If you are in a web site and a pop up tries to get you to click on it for a scan or update DO NOT click on it or respond in any way. You probably are dealing with spyware or at least you will once you click on it.

One final note: Never install a beta version of any software or shareware unless you know what you’re doing. You need to be prepared to reload your system with these basically untested versions. They can mess up your good setup. Shareware is great but it can also contain unexpected surprises such as Viruses or spyware. It may not be written well and can cause your system to slow down, freeze or worse. This is called malware. Partially loaded or defective software of any kind can really cause problems. Never shout off your computer in the middle of installing software.

All computers maintain system time from an internal real-time clock chip. These devices are generally relatively low-cost and as a consequence tend not to keep good time. In fact, computers are notorious for providing inaccurate time and can drift by several minutes each day. This has serious consequences for networked computer systems and applications. Each computer can have wildly differing system times, which can be totally unacceptable for transaction processing applications. A solution is available in the form of network NTP servers. These allow all the servers, workstations and other infrastructure on a network to synchronise to a single accurate time reference. A Time Server obtains precise time from an external time reference and maintains an accurate internal time. This time is then made available to network clients for synchronisation.

The Network Time Protocol (NTP) is the standard means of network time synchronisation. The protocol defines a number of messages, or packets of information, that are passed between a time server and a client in order to achieve synchronisation. Most operating systems, including Microsoft Windows, LINUX, UNIX and Netware have integrated NTP or SNTP client software. Client software is also freely downloadable from Internet sites under the GNU public licence.

Configuring client software is extremely straightforward. Minimally, the client software only requires the DNS name or IP address of the time server that the client is to utilise for synchronisation.

There are many public NTP Servers freely available on the Internet for synchronisation, generally provided by Physics labs or Government departments. However, there are a number of advantages associated with having a local server on your network. Firstly, a local server will reside inside your firewall and pose less of a security risk than an Internet based server that requires ports to be left open in your firewall. Local servers are more accurate by having a direct connection to a hardware reference clock. Also, a recent survey showed that many Internet based servers are configured incorrectly and can provide inaccurate time.

A number of hardware reference clocks are available to time servers, the most common and accurate being GPS (Global Positioning System). GPS is most widely used for navigation purposes, but can provide time accurate to within nanoseconds. However, in order to receive GPS signals an antenna is required that needs to have a good view of the sky, ideally on a rooftop. Therefore, installation costs can be an inhibiting factor. Alternatively radio time and frequency broadcasts can generally be received indoors close to the host. Therefore, installation costs are kept significantly lower. However, weather, ground topography and other forms of interference can severely affect radio broadcasts. Radio time references are also not as accurate as time sourced from GPS.

In summary, it is very simple to synchronise computers and computer network infrastructure to a single accurate time reference. GPS and radio NTP Time Servers are widely available as off-the-shelf solutions to the problems of maintaining accurate network time.

PCB stencil online quote

When Gmail first threw its hat into the email ring a few years ago, its service was open only to those who had received an invitation. Now, however, it’s free and has exploded into one of the most popular email services available – thanks to Google’s trusted brand name, its simplicity, the huge amount of storage space available for absolutely free, extra features (such as POP3 access), embedded web and video chat, and so many more! Is it any question, then, that millions of people are already using Gmail – even though it’s a relative newcomer on the email scene?

And though Gmail’s spam filters are among the best available, there is a chance that, at some point, you’ll receive unwanted email – and it might even be from a Gmail address. In such an instance, your best bet is to use Gmail’s own reverse email search; it’s easier for Gmail, after all, to search its own records than to have an outside source looking in. See what you’re able to discover about the sender. (Gmail is especially attractive to those wishing to remain very much anonymous, because the headers in any given piece of mail are stripped of any and all IP information. Thus, the stalker or hacker believes himself or herself to be secure.)

Even if you don’t have much luck, or any at all, you are far from out of options. In fact, now would be a good time to check out one of the many free independent reverse email search engines available online. When using these sites, the key is to remain tenacious – because it may take a good while before you produce results. Giving up is the last thing that you want to do; after all, even if the reverse email search engine you are using isn’t having any success at all, bear in mind that there are those services which, for whatever reason (and there exist a few possibilities), have more success than others!

If you are still having little to no success, or if the email received was of a particular harmful or malicious nature, you might want to consider contacting a third party for some needed extra help. I am referring to professional investigators who specialize in online matters, since they have tools at their disposal not necessarily available to you. Every step taken online leaves a ‘footprint’ – data that can be tracked and which will inevitably lead to the person who has been taking the steps all along. This is true even if the person in question is using dial-up or a handful of proxies; while these factors could slow down a search, they are never able to stop a search in its tracks altogether!

Private investigators often have access to what is known as the “deep web” – information not available through conventional means such as, say, a simple Google search. So always remember that the only way to ensure your subject gets away is for you to run out of steam and simply give up. Otherwise, you should inevitably be able to find the information that you are looking for! Best of luck!

The Internet is an amazing accomplishment in several respects. It contains an enormous amount of information; it has revolutionized business, education, and everyday life; and it’s still running on a widely outdated infrastructure.

The Internet, these days, is caught in an interesting cycle. The more widespread the adoption of the Internet is, the more information gets added to it. The more information it holds, the more useful it is and the more people use it. The trouble with the growing usage of the Internet and the growing amount of information it allows access to is that the structure of the Internet isn’t keeping up. In other words it’s not much easier to gain access to the information the web holds now then it was when it first started. Sure, the web has undergone some helpful changes such as starting to standardize the way pages are coded and rendered. And, there are some promising changes on the horizon. For example, the implementation of HTML 5 will make it easier to code and-by extension-parse information semantically. Similarly, Google is in constant development of projects (FriendConnect, OpenSocial, Google Webmaster Tools, etc.) designed to standardize the way information is stored and used on the Internet. There is also a small but growing trend among sites to open up systema#tic access to their data by way of an API, and there’s an ongoing movement to implement semantic technologies such as RDF and OWL.

The tricky thing about each of these strategies is that they are fairly costly to actually put into production. For example, the ideas behind HTML 5 were generated in 2004 and it’s taken four years to publish a working draft of the specification. Once a specification for HTML 5 has been agreed upon it will still take countless hours of development to get browsers to properly render the syntax, countless hours of research by website designers/programmers to learn and adopt the new syntax, and countless years before all the websites available in the public domain are using HTML 5. Even the adoption of an API technology like OpenSocial can require months or years of changes to a site’s data infrastructure before they can be rolled out; and that’s after Google invested their own time and money to develop and market the API in the first place. So, it would seem that-in order for the semantic web to happen-there needs to be one or more technologies that allow companies to expose their data in a systematic way, at a low cost, and without a lot of implementation work; and there are a couple of companies that are working towards filling these sorts of requirements.

Mashery

Mashery (www.mashery.com) provides on-demand API infrastructures. By offering a full-service solution-one that includes documentation and maintenance-Mashery allows companies to quickly implement an API for a monthly fee instead of hiring one or more engineers to build an API from the ground up. As Mashery, and companies like it, gain popularity it will allow other website owners to systematically expose their data through APIs at a lower cost. The lower cost of creating an API will encourage more companies to hop on board and will, hopefully, bring about significant changes in how data can be interacted with.

Mozenda

Mozenda (www.mozenda.com) is a data management platform that allows users to combine and use data from multiple sources. With Mozenda, users can set up agents that routinely extract data from nearly any website. The information, once collected, is stored on one of Mozenda’s secure servers and can be exported in a number of file formats or systematically accessed through Mozenda’s API. By allowing users to both gather data and access it through a call, Mozenda has essentially created the ability create an API for nearly any website.

“Angelina Jolie nude” is one of the most searched for terms on the internet so it is no wonder why hackers decided to exploit this with a newly discovered spyware trojan.

This latest threat is being spread via a spam email message with a clickable link inserted within the message. The message claims to have uncovered some rare adult video footage of her and in many cases the message will also contain a picture of Angelina Jolie nude. But what happens when you click on the link is you are directed to a spyware website and a download is immediately initiated prompting you to download and run the video file which then installs a trojan downloader onto your computer.

What is particularly unnerving is the fact that the programmers of this latest spyware threat have gotten so clever that they mention that the email was sent via an MSN Offers program, thus tricking the user into thinking that the email is legit.

This latest threat is a prime example of why you shouldn’t open up any email attachments or click no any links contained within an email unless it is from someone you know and trust and even then, if the email looks at all suspicious contact the person from which the email came from to verify, preferable by phone.

This is very important and is just one of the steps you can take to protect yourself when online.

Here are 5 additional steps you can take to protect yourself from spammers and spyware:

1. Ensure you have a proven and reputable antivirus and antispyware software running on your computer and I am not talking about the freebies either – they just aren’t very effective.

2. Ensure your computer is kept up to date with the latest security patches – Microsoft Windows users this means turning on Automatic Updates.

3. When downloading any type of file, even from a legitimate source, make sure you save the file first to your computer instead of just running it from the download location. This gives your antispyware and antivirus software a chance to scan it first.

4. Avoid P2P programs like Kazaa and Limewire – these types of sharing networks are inundated with spyware infected files.

5. Stay away from pornographic and gambling related websites. This should be self explanatory.

All of us as Internet users need to be responsible when we’re online or in our inbox so that we can do our part to help limit the spreading of malicious spyware and malware.

And if you get an email claiming you can see a rare adult video of Angelina Jolie nude, report it to your ISP and then delete it or risk having your computer inundated with spyware.

Does your computer lag or does it seem to have any unusual behavior, if it does chances are your computer is infected with a virus. To help you with solutions to computer viruses I have answered some questions people ask me about getting rid of viruses.

1.)Whats is a computer virus?

Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk. Viruses are most easily spread by attachments in e-mail messages or instant messaging messages. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files, this is why most viruses come from downloading movies, music, illegal programs and most of all from pornographic material.

2.)What are other names for a virus?

You may have heard of malware, spy ware, Trojans, trackers, hijackers, ad ware, etc… these are just subsections of viruses.

3.)Symptoms of a virus?

After you open and run an infected program or attachment on your computer, you might not realize that you have introduced a virus until you notice something is not quite right.
Here are a few primary indicators that your computer might be infected:

Your computer runs more slowly than normal,

Your computer stops responding or locks up often,

Your computer crashes and restarts every few minutes,

Your computer restarts on its own and then fails to run normally,

Applications on your computer do not work correctly,

Disks or disk drives are inaccessible,

You can not print correctly,

You see unusual error messages,

You see distorted menus and dialog boxes

You are BOMBARDED with pop ups,

4.)What are some solutions to computer viruses?

The perfect solutions to computer viruses are purchasing a quality virus program, and staying off unwanted sites. Then your computer and your privacy is secured.

5.) What is the best virus protection for me?

Even if you do not have a virus, or already have one, purchasing a quality virus program is the best solution to computer viruses. I have mentioned the best solutions/products for your computer virus problems below.

6.)How easy is it to use the software?

You can have the software downloaded and running within ten minutes. It’s that easy! You can even set it to run regularly – you do not even have to know it’s there. It will just run regularly to clear out new viruses that might have somehow crept in.

7.) Why should I pick any of these virus protection programs?

Well that is a good question. What is special about these programs is that they attack viruses before the virus attacks your computer. Compared to Norton Anti virus, which lets the virus attacks the computer and then kill the virus and go after its sources. The negative about this is, if u let the virus install it self, its almost impossible to kill its roots. Also the programs I have listed below have real time protection. Real time protection is denying the virus from entering your computer, therefore you can surf any website you want.

8.) Okay, but still, why should I pick these programs? (convince me more)

Alright, well Big brand name programs such as Norton or Mcafee, come out with new editions each year, which means that you need to buy the latest version in order to keep up with the virus world. In comparison the programs i mention, you do not need to but the new version every year, the programs virus definitions are auto updated. Also these programs are a lot more affordable than brand name programs. THE PROGRAMS GET THE JOB DONE!!

My computer had been attacked in the past, it deleted all my work from my computer, i could have lost my job!, So i took the extra step and purchased all of theses programs. If you are confused or not sure with program suits you best, all these programs offer free trials. Hope you found questionnaire about solutions to computer viruses helpful, you can learn more at:

We’ve all heard the cliché “There’s no such thing as a free lunch.” This is as true on the Internet as anywhere else. Adware and spyware programs, also called malware or trackware, infect 9 of out 10 Internet-connected computers. Spyware can slow your computer to a crawl, corrupt your hard drive, or expose your private information. The most common way it gets on your computer is when you are downloading something else that claims to be free.

What is spyware and how did it get on your PC?

• Adware and spyware programs, also called malware or trackware, quietly and secretly monitor everything you do online, and can communicate your activities to a third party such as an online advertiser.
• Spyware is commonly installed on your PC as a hidden addition to a legitimate program, by visiting websites, or through spam email.
• Unlike the instant impact of a virus, well-written spyware and adware programs never reveal their presence on your PC.
• Pop-up ad problems, a different homepage that you can’t change, and a slower PC or online experience are indications of a spyware problem.
• No one is immune from Spyware infection. A recent study by EarthLink and Webroot found an average of 26.5 spyware and adware traces per SpyAudit scan.

Where does spyware come from?

Spyware is software that collects personal information from you without first letting you know what it’s doing and without letting you decide whether this is OK or not. The information spyware collects can range from all the Web sites you visit to more sensitive information like usernames and passwords. You might be the target of spyware if you download music from file-sharing programs, free games from sites you don’t trust, or other software programs from an unknown source.

Spyware is often associated with software that displays advertisements, called adware.

The extra processing required to track you or to display advertisements can tax your computer and hurt your system performance.

What are the signs that your PC is infected with spyware?

• Your homepage is reset to an undesirable website change it back.
• Problems with pop-up ads.
• Slower than usual PC performance or Internet access.
• Redirected web search results.
• Strange additions to Favorites list or start-up menu.

Over the past several years in the course of repairing countless numbers of computers, IT professionals have identified thousands of spyware files, folders and Registry keys. Here’s a list compiled by experts of Do’s and Don’ts for protecting your systems from spyware and viruses.

Do

• Run up-to-date anti-virus software. We recommend Kaspersky Internet Security(TM) or Kasperksy Anti-Virus(TM) (www.kaspersky.com).
• Run up-to-date Spyware monitoring software, such as SpySweeper(TM) (www.webroot.com).
• Update the above-mentioned software manually if you are a dial-up user.
• Clean off temporary Internet files from your computer.
• Be wary of files you download off the Internet.
• Supervise children – sites they visit and files they download.
• Download music using legitimate pay-for-music distribution sites such as Napster, Rhapsody and iTunes.
• Have your system maintained by a certified IT professional every 3-4 months to insure your investment lasts 3-5 years.

Don’t

• Download any type of free file-sharing utility (music, games, applications) such as KaZaa, Limewire, Bearshare, P2P, Grokster and Morpheus.
• Click on any type of pop-up advertisement – always close them immediately using the “X” in the upper right corner of your browser window.
• Accept email attachments from people you do not know.
• Download freeware and shareware (free programs on Internet) unless you know they are from a legitimate company.
• Ever allow website install ‘plug-ins’ to your Internet browser unless they are from a legitimate company such as Macromedia or Real.
