Please go to the malware
forum and follow the instructions at the top....Especially the CLICK HERE
That will give you several steps that will help you clean up 70 percent of all problems by yourself. If at the end of the process you are still having difficulty--and you may not be-- then post a hijackthis log in THAT
If you are still having problems after getting a clean bill of health from the malware expert, please return to this
thread. Neil, please do NOT give Malware type advice on the boards unless/until you go through GeekU training. Non-staff members are not allowed to post advice for any malware-related problems. thank you
