In the old days, like 10 years ago, one of the only ways to catch a computer virus was to transport it from hard drive to hard drive via corrupted files on floppy disks, as the viruses were embedded in files and programs.
These days everyone and everything is online, and virtually every 13-year-old kid with a mischievous streak and a computer in the den can start a global virus panic. Things will likely get worse before they get better as computers and the Internet become more and more synonymous.
A lot of people are already connected to the Internet around the clock, leaving themselves open to all kinds of unwanted visitations. You can pick up a virus by downloading and opening untested programs and files, through your e-mail system, or through almost any contact with the outside world. Hackers have found ways to break into your home computer, which leaves them free to plant viruses or, worse, to access your personal information.
There are more than 2,300 different viruses in circulation, most of which are just variations of a group of very basic viruses. Some are intended to annoy, and others to destroy.
There are dozens of antivirus applications on the market that can scan incoming information for viruses, but with new viruses surfacing every few weeks, youre really only as safe as your last upgrade or patch. Fortunately these patches come down the pipe every few weeks as well.
The problem is that you cant really protect your computer against viruses that dont yet exist. You can adjust your security settings to alert you of potential problems, and many security programs can recognize the viruses that are similar to other viruses, but at the end of the day youre going to want to stay on top of things. An ounce of prevention could save you a pound of cure. And a bundle of money.

The CERT Coordination Center is a division of the Software Engineering Institute, a federally-funded research and development organization operated by Carnegie Mellon University.
If theres a new virus out there, or a security hole is discovered within software, this is the place to go to learn about it, and to find out how to protect yourself.
How real is the risk you ask? CERT began tracking security incidents back in 1988. There were six that first year. The following year there were 132.
In 2000 there were 21,756. In 2001 there were 52,658. In the first quarter of 2002, just three months, there were 26,829. And these are only the incidents that are reported.
"Incidents" could refer to hacks and information thefts, vulnerabilities within software, computer viruses almost anything that compromises security.

This site is more for IT managers than home users, but its an interesting visit nonetheless. After all, the information posted on this site is the same information used by the Web companies you download information from and trust your credit card and personal information to. Its scary stuff sometimes, but overall this site is reassuring.
www.symantec.com
Symantec is the company behind Norton Antivirus 2002 software, which also happens to be the current ZDNet Editors Choice. For years Nortons has been one of the most trusted security utilities on the market, and it keeps on getting better.

McAfee is another well-trusted antivirus service. Their latest offering, VirusScan 6.0, was not as highly rated as Nortons by ZDNet, but theres no denying that its a good tool. One service they offer is VirusScanOnline, an online subscription service that provides you with around the clock virus protection. Theres a small download at the beginning, but after that it upgrades and patches security holes automatically. In other words, you dont have to visit a Web site every two weeks to download new patches to protect yourself against the latest virus.

Panda antivirus software, Swedens latest addition to the high-tech market, is quickly gaining recognition as an effective and affordable solution to the virus epidemic. While it didnt rank as highly as the Norton product did at ZDNet, it has received a lot of praise for being easy to install and configure, and for making it easy for users to update and upgrade.
