Pest Trap is a corrupt anti-spyware program that uses false positives. It
does not actually detect parasites, but targets harmless system and software
objects as threats in attempt to trick the user into purchasing the full
version of Pest Trap. The application itself is a clone of the infamous
SpySheriff rogue and similar programs such as SpywareNo!, SpyDemolisher and
Spyware-Stop. Pest Trap is an unsolicited program. It may harm your system
and violate your privacy!
