There's a spyware forum which discusses the plusses & minuses of each anti-spyware program. PestPatrol has been reported as being "faulty" by these specialists. Specialists who are themselves spyware programmers. You should also be aware that some anti-spyware programs have spyware/adware themselves as reported by that forum. There's also scam versions. So be wise to choose your spyware program carefully!

Ad-aware & spybot are recommended. See WARNING: Viruses on network you should be aware of! (click on link)

This type of thread is a typical example of new members not reading the forum rules before their 1st post; ie: searching for their answers before posting.
