Recently PC Magazine conducted a survey that asked participants to rate their broadband ISP services. We found out that many users don’t completely understand the seriousness of potential threats or how to protect their PCs. The following are responses to the top five security misconceptions we encountered.
I don’t keep important things on my PC, so I don’t have to worry about security.
There was a time when this statement was partially true, but that time has long since passed. Current viruses, worms, and other threats, including the famous Love Bug, Nimda, and Blaster, spread blindly across the Internet to thousands or millions of PCs in a matter of hours, without regard for who owns them, what is stored there, or the value of the information they hold. The purpose of such attacks is nothing less than to wreak havoc. If you ignore the reality of these attacks, you are certain to be hit at one time or another. Even if your computer is not attacked directly, it can be used as a zombie to launch a denial-of-service or other attack on a network or to send spam or pornography to other PCs without being traced. Therefore, your civic responsibility is to protect your PC so that others are protected.
I can protect my PC if I disconnect from the Internet or turn it off when I’m not using it.
Wrong. If you connect to the Internet at all, you are a target. You could download a virus when you connect and not activate it until days later when you read your e-mail off-line. Even if you rarely connect to the Internet, you can get a virus from a file off of a network, floppy disk, or USB flash memory drive.
I can protect myself from viruses by not opening suspicious e-mail attachments.
