My laptop got infected through a pendrive, the infection went undetected through Avast (mostly because it was not updated for not having internet access these days). Later I installed SuperAntiSpyware which detected some spyware and removed it, similar thing happened with Drivesentry scan. Unfortunately, I do not have the details of the detections. Since Avast could not work, I decided to try Avira. I installed Avira's latest free edition on my machine, and scanned the machine, it did not find any detections yet my computer started showing sickness symptoms. Now, the situation is that, I do not have any recommended antivirus apart from Spyware Doctor and DriveSentry. In spite of disabling DriveSentry for some time, the certain applications wouldn't run including Spyware Doctor. The scumware doesn't allow installation of Avast/Avira or any other antivirus options (Not even in Safe Mode...in fact when I try to run the machine in Safe Mode, it crashes and restarts, couldn't capture the blue screen message)
So the thing is the infection is not allowing to install any antivirus, does not allow many applications to run including some media players, the task manager and registry editing is disabled (it gives a message: Task Manager has been disabled by the Administration). Although in my tries I suspected of some generic activity through Content.IE5 folder. Preferrably I do not want to format the PC.
For your convenience, I've attached the HJT report.
Please suggest the remedy. Thanks in advance.
