HijackThis & Autoruns
HijackThis & Autoruns are free system tweaking utilities that are very useful in the
removal of various pests, particularly of the adware/spyware/browser hijacking
variety. However, neither has automated detection or removal capabilities
and requires expert knowledge to be used effectively (and safely.) It is
recommended that these programs be used only under expert guidance. The
current version of HijackThis, which now belongs to TrendMicro, can be
downloaded by clicking here. The current version of Autoruns from Sysinternals (which is now owned by Microsoft) can be downloaded here.
