Just One, Not Two -- Never use two
anti-virus products at the same time. Completely uninstall one before
installing another. Use the vendor's uninstall utility or if not
available, use the Windows XP add/remove software tool in the
control panel.
Patches & Updates -- Anti-virus software is only as effective as its most recent
update because it is inherently reactive treating "known" threats. So
when you install anti-virus software, go to the
vendor's web site and update the program and virus definitions immediately
and then turn on the auto update feature (if it has one). If you want to be
ready for the next big bad thing before your anti-virus signatures
can be updated, consider Zero-Day Protection.
Get Online Protection Too -- Consider using an Internet service provider or email
service that includes server side anti-virus and spam email filtering as a
second layer of defense. If possible, use different anti-virus software
on your home computer than your ISP or service uses on their servers.
Consider a Gateway
-- A Broadband Gateway product between
your modem and network can screen out viruses before they hit your
computer(s).
Spyware & Trojan Horses --
Some anti-virus software products now include
anti-spyware and some anti-spyware products have added anti-virus.
In addition, some of these products include anti-trojan, anti-worm
and other anti-malware features. Before relying on a single security
product, carefully review the vendor's list of features and study
comparative test results if available. See
