Much of the time, spyware relies on persuading unaware or credulous users to download and install it by offering some kind of seemingly enticing bait, such as a prize, free money, a free service, or a free service that’s “better” and supposedly gives you a leg up on widely known legitimate software or services. 99% of the time, you can assume that it will not help in any way.

Here is a list of known spyware applications and a list of known spyware creators/vendors . Check these lists if you run across a program you want to install, but don’t really know anything about its origins or appear on unprofessional websites. If the software does not appear in the product search, it is either too new, too obscure, or not a threat.
