Hello there and welcome to BleepingComputer.
I think the best course of action for you, based on the amount of malware it would appear is present, would be to post a HijackThis in our forum for analysis from an expert. Please follow our Preparation Guide For Use Before Posting a HijackThis Log
; running all of the scans before posting your HijackThis log. Do not post your log here, but instead use our HijackThis Logs and Analysis Forum
After posting a log you should NOT
make further changes to your computer except those that are advised by a member of the HijackThis Team; doing so can cause system changes that may not be visible in your log. Please be patient whilst waiting for a response, our HJT Team is currently very busy, and as we try to deal with logs on a "first come first served" basis, you may have to wait a short while.
