So you have spyware, and you want to get rid of it. You do some research, and find an anti- spyware program. Unfortunately, this is not the end of your worries.

Malicious programmers have released a large number of fake anti-spyware programs. They use web banner ads to tell users their computers have been infected with spyware, and tell them to purchase anti-spyware programs that remove these harmful parasites. But, these harmful products do not get rid of spyware. In fact, they can actually add even more spyware!

We've seen an increase in this type of activity lately, and as a result, there is increased concern. Some of these anti-spyware programs promote themselves as being antispyware, antivirus, or registry cleaners. They will often feature popups telling the users to install their product. Software like this is often referred to as rogue software.

Here's a list of some of the known anti-spyware scam programs:

* AntiVirus Gold

* ContraVirus

* Errorsafe (also known as system doctor)

* MacSweeper

* PAL Spyware Remover

* Pest Trap

* PSGuard

* SpywareStrike

* Spyware Quake

* Spydawn

* Spylocked

* SpyShredder

* Spy Sheriff

* Spy Wiper

* UltimateCleaner

* WinAntiVirus Pro 2006

* WinFixer

* WorldAntiSpy

How you can prevent this? For starters, do not install freeware products that claim to be anti-spyware. It's fine to use products that offer a free scan, but you will want to eventually go with the paid version. Fortunately, legit anti-spyware programs don't cost too much money. It'll probably run you about $25 to $50. Well worth it, when you consider the piece of mind of getting a reliable piece of software.
