Use anti-spyware tools

Spyware is a common virus source, but you can minimize infections by using a program that identifies and removes spyware. But be sure not follow email links claiming to offer anti-spyware software, like email viruses, the links may serve the opposite purpose and actually install the spyware it claims to be eliminating. Purchase your protection software from a known vendor. Most antivirus software includes an anti-spyware option; be sure you enable it.
