Virus Protection

If your computer connects to the outside world in any way, you need to worry about virus protection. If you use email, share disks (even CDs or DVDs burned by others), or browse the Internet, you're vulnerable to a virus attack. Some viruses are relatively innocuous, only copying some files and maybe changing some minor information on your computer, but most viruses are at least somewhat destructive. Some can completely wipe out your computer right after they send a copy of the virus to everyone you've ever corresponded with.

Although Outlook now has significantly higher levels of virus protection than in previous versions, just because you use Outlook with the object model guard and restriction on programmatic sending of email, it doesn't mean you're safe. One of the most rampant viruses of this past year, the Klez virus, used its own SMTP engine. It didn't trigger the security prompts in Outlook at all. In addition, it spoofed addresses so that no one really knew where the original infection started. Klez searched your hard drive and picked two email addresses at random. The first email address would be marked as the From field in the email it sent, and the second address would be inserted in the To field of the email. If anyone you knew was infected with the Klez virus, you probably received emails from other people accusing you of sending them a virus. There's a good chance it wasn't you. It was Klez pretending to be you.
