J.D. BIERSDORFER: Antivirus software can protect your machine from certain
tools that hackers have been known to use, like Trojan horse programs (designed
to steal passwords) that you may get in the form of an e-mail attachment. A
hacker trying to break directly into your computer over the Internet, however,
can thwart an antivirus program.
Antivirus software can stop some types of spyware, but not all of it. Spyware
is classified as unwanted programs on your computer (installed with or without
your knowledge) that can do a number of things including pestering you with
unwanted advertising, or even more sinister actions like blocking your access to
certain Web sites.
Adding a dedicated anti-spyware program is another way to strengthen your
PC’s security. Using a firewall — software that blocks unauthorized access to
your computer from Internet intruders — is another way to further shore up
defenses. Firewalls also come built into broadband routers, and both Windows and
Mac OS X include integrated system firewalls.
Most programs labeled as “Internet security suites” include antivirus and
antispyware programs, as well as a firewall with more configuration options and
other features like parental controls. These software packages typically cost
$50 or more, but if money is tight, you can find free alternatives around the
Web. Microsoft has free antivirus
and antispyware programs and plenty of others are listed on the
Gizmo’s Freeware site.
Sites like onguardonline.gov and
getsafeonline.org offer much more
information on keeping your computer and your personal information secure.
