Tools To Keep Your Computer Clean
Ad-Aware: Ad-Aware is a free program that is used to find and remove spyware and adware from your computer. We recommend that you run this program weekly.
AVG: AVG is a free anti-virus program. It works VERY well and uses very little of your system's resources so it doesn't slow down your computer.
Spy Sweeper: Spy Sweeper is another program that removes adware, spyware, and viruses. It isn't free, but it's well worth the money as it finds stuff that other adware and virus scanners don't.
