Well,basically first rescue exit are on-line scanners. I recommend that you check your machine with Command On Demand,BitDefender or HouseCall (check my page for direct links).
If the viruses cannot be cleaned because they are resident,try terminating them manually (terminate any suspicious processes in Task Manager) and repeat the scan. You can try Rogue Process Xterminator or similar feature in AEC which can terminate over 120 known resident malwares. Not sure if any of them is on your PC,but it can’t hurt if you try. Then again repeat the scan with online AVs mentioned above when you terminate them.
