Virus Software

Windows XP SP 2 also direly warns you if you have no antivirus software installed—but unlike the firewall example, this time Microsoft doesn’t provide any. The Virus Protection feature, it turns out, is not an inoculation but simply an alert.

However, if you click the Recommendations button (visible in Figure 10-2), you’re taken online to a Web page filled with free time-limited trials of various antivirus programs.

Tip

Some antivirus programs not listed by Microsoft on this page aren’t just trials—they’re actually free. For example, at http://www.grisoft.com, you can download AVG Free Edition, which is free antivirus software. It’s a welcome alternative to better known but much more expensive products like Symantec Antivirus and McAfee Virus Scan.

Once you’ve installed antivirus software, the Security Center will smile on you with a happy green ON “light” next to the Virus Protection heading. (That is, it will if it recognizes the antivirus software. As with firewall software, lesser- known brands and versions released before Service Pack 2 may not be recognized.)

You’ll have a much more relaxed computing life once you’ve protected your PC with this kind of software. Consider antivirus software part of the cost of doing business, and remember that you are the best defense against viruses. Don’t open email attachments, no matter how juicy they look.
