83. Install and Use Antivirus Software
Many antivirus programs are available for the Windows operating system: Norton Antivirus, Computer Associates EZ Antivirus, PC-cillin, and Kaspersky Anti-Virus, just to name a few. The antivirus software you actually use (and purchase) is really up to you. Although tests show that some antivirus programs are better at detecting and removing obscure viruses, having any antivirus software that is up-to-date is an important aspect of protecting your computer from malware invasion.
Most broadband Internet connection providers such as Verizon, Time Warner, AOL, and others provide you with free antivirus software. Some companies even provide antimalware suites that include antivirus, antispyware, and antispam products. Check with your Internet service provider before buying antivirus software because you might be able to download it for free.
Some antivirus programs are bundled in security suites that also include antispyware, spam email filtering, and even firewall software. Examples include AVG Anti-Virus plus Firewall Edition and Norton Internet Security 2005 AntiSpyware Edition. Because Windows XP already includes a personal firewall, you don't necessarily need to purchase an antivirus suite that also provides a software firewall. However, purchasing antivirus software that includes spam filtering and antispyware capabilities does make it easy in terms of having to update only one antimalware product instead of separate products for virus detection, spyware detection, and spam filtering.
Most antivirus software manufacturers allow you to download a trial version of the product. You can then purchase a license to continue using the product. Some antivirus programs also allow you to buy multiple licenses at a discount, which is ideal if you have several computers on the home network that need antivirus software. Remember that every computer needs its own license for the software. Don't be afraid to try different antivirus software. The products differ in terms of ease of use and effectiveness, so it is a personal choice. Check out reviews on the Web related to antivirus software and choose the best product for you and your computer.
When you run your antivirus software, you can continue to use the computer, but I think you will find that your computer will run slowly. It makes better sense to run the virus scan when you are not going to use the computer for a period of time, such as at night or during lunch.
Install and Use Antivirus Software
If a virus cannot be removed, the report provided by your antivirus software will detail this information and provide the name of the infected file or files. In some cases, you might have to update your antivirus software to clean the virus from your system. In other cases, you might have to follow special instructions provided on your antivirus company's website or download a "cleaning" program that removes the virus, worm, or Trojan horse that cannot be removed by the antivirus software.
