Adequate protection at no cost:
A
free suite
Though lighter in features than most suites, these three
online programs will probably suffice if you practice
careful computing, and they won’t tax your
computer’s resources. The Avira AntiVir Personal
Edition Classic 7 (replaced by Free Antivirus 8, which
claims faster scan speed and other enhancements)
provides good virus protection. But it might take a bit
longer than the best suites to recognize a new virus or
might occasionally flag a safe file as a threat.
Microsoft Windows Defender, built into the Vista
operating system and available as a free download,
rivaled the best suites against spyware and adware.
SPAMfighter Standard is a very good supplement to the
spam filter in your
e-mail application if you require it.
Best choice for optimal protection:
BitDefender
Internet Security 2008 $50
Consistently very good in performance and fairly rich in
features, including the best array of antivirus tools of
the high-rated suites. Drawbacks compared with most
suites include a few more false positives and a bit less
information about tagged sites, requiring a little more
research than others to determine whether a site is in
fact a threat.
Fine choice for a newer computer:
McAfee
Internet Security Suite with SiteAdvisor $50
Best used with at least 2 gigabytes of memory, found on
newer computers. This suite is feature-rich, performs
comparably to BitDefender, and is among the most
effective against spam and phishing. Its $40 annual
renewal fee is less than half that of the Kaspersky. But
it’s a little less effective than the other top
performers at detecting spyware and adware.
