I noticed in your other post you said that you're close to formatting your HD...well before you do that, try this!
I suggest posting a HijackThis log in the HJT Logs and Analysis Forum. Here is a link to that Forum: HJT Forum
Please follow the preparation directions and try not to alter your system until you receive help from one of our HJT Team Members. These preparation directions have you run several scanners in order to remove most of the malware on your system and this may help alleviate immediate problems!
The preparation directions are found at the following link:Prep Guide for Posting HJT LogsPlease note: Do not try to fix any problems with HJT yourself. This is an advanced tool and requires expert analysis.
It may take a couple days to get a response, but please be patient. Once someone gets to your log you will be in good hands! I hope this helps!
