SpywareBlaster is NOT a removal program, it is a protection program. Leave it on the computer and keep it updated.

Ok, have gone through the log again...I missed this entry
O16 - DPF: {56336BCB-3D8A-11D6-A00B-0050DA18DE71} - http://software-dl.real.com/13cf9c64...p/RdxIE601.cab
it is probably the culprit, though there could be others which just do not show in the log.

You need to go to this thread
I know that you have done most of these steps before posting here...but I would like you to do them again...EXACTLY as PP directs. Including the online scans, and be sure one of them is Kaspersky. Please also use ATF-Cleaner in safe mode as he instructs and also the Spybot and AVG anti-spy programs. Let them fix everything found, save the AVG log.
Reboot to normal mode, run a NEW HJT scan and be certain that you close ALL browsers when doing the HJT scan. Post back here with the HJT log, the Kaspersky log and the AVG anti-spy logs.
