according to a test of magazine pc professional
Pest Patrol acchieved the best result when confronted with
an almost unreal, very malicious mix of trojans and spyware ...

Spybot ranked 2nd and AdAware 3rd ...

I made the experience that Spybot found items on a system
cleared with Adaware but it happened also viceversa ...

doublegalloppel seems to be no idle effort thus ... :D ... ~*~
