Fighting spyware (beyond antivirus)
You might think installing a good antivirus program and firewall on a Windows PC means no more worry. Your PC is now supposed to be immunized against catching a computer virus. But, unfortunately, there are an increasing number of Internet nuisances out there that can bypass those defenses. Spyware applications and spyware tracking cookies often skip right past the "behind the curve" antivirus program you inherit from the computer dealer when you buy a new Windows PC.
If you use a Mac, you might congratulate yourself for being immune to a number of hostile programs that mistake you for a Windows user. Bad stuff targeted for Windows just bounces harmlessly off your computer. But whether you use Windows or OSX, visiting a website in your web browser opens the door for a wide number of processes to access your computer. Mac users, before you get too overconfident check out this list of Macintosh keyloggers, trojan horses, and backdoor spyware.
