How to Protect Your Computer from Spyware and Adware?

Without help, you have no way to prevent adware or spyware. Old antivirus programs don't even prevent adware, since they didn't consider them viruses or worms. First, you usually give permission to install adware, although you do so unwittingly because adware and spyware pushers are deceptive. Second, adware doesn't behave like a typical virus or worm. They don't usually do actual damage to your computer, other than wrecking its performance, and they don't spread themselves using your address book. (Although some kinds of adware can break your anti-spyware tools.)
Things are changing for the better, though. Most popular antivirus products now include adware and spyware scanning. For example, the latest versions of McAfee VirusScan, Norton AntiVirus 2004, and Trend Micro PC-Cillin 2004 now scan for some adware and spyware.
Also, some Internet service providers (ISPs) are introducing protection from adware and spyware. For example, America Online (AOL) announced in January spyware protection as an enhancement for AOL 9.0 Optimized. EarthLink also provides adware and spyware protection through the latest version of its software. Of course, to take advantage of the built-in protection that antivirus products and ISPs provide, you have to update to the latest versions, and keep the anti-spyware/adware signatures current.
