Welcome to G2G!!!!!!
It seems like you would first benefit from visiting the Malware Forums. Even though it seems like its an Operating System or Software problem, it has a good chance of being a malware issue or related to malware in some way. Also, they have other tools to help you clean your system other than the ones you have run already.
Furthermore, malware might be in the shadows lurking and if any changes are made to your computer, it might strike at any moment if it sees a vulnerability. So please begin
HERE. Don't forget to add a link to the malware thread so the malware staff can follow up on steps you have already taken.
When you complete the malware part and your computer is officially clean, come back to this thread if you are still experiencing the issues.
