For the computer literate only ........
For some good tools go to
http://www.sysinternals.com/download these products:
rootkitrevealer, process explorer and autoruns
also google for an app called hijackthis
it shows you BHO’s ADS’s and other IE related problems
anything that cant be seen by your AV or antispy product like adaware /spybot/ ms antispyware can be found with these if you’re good at sniffing out rats in a windows system.
Any processes you haven’t heard of can usually be googled for character references.
Once you find something, removing the infection can be a pain in the bum, you might need to build a bartpe boot disc so you can do an offline disinfection.
If the above dont make no sense dont bother trying to understand it.
If you asked your local computer shop of PC World about the above you`ll see a blank face then you`ll be assured that Norton systemworks will sort it all out for you
