Recently my system was infected with a virus through a pen-drive...
I have a McAfee anti-virus - VirusScan Enterprise ver 8.5.0i installed on my system...My anti-virus was not updated at that time..
So it did not detect a virus..I used the pen-drive on another system with an updated version of the antivirus and it detected 2 Trojan's 1."SCWHsot.exe" in the System32 folder
2."Autorun.ini" in the Pen-Drive
Subsequently I updated my anti virus and scanned the system but my Anti virus didn't report an infection..
I found a few problems at that time - e.g
1.In the Tools tab - The folder options was missing
2.I couldn't start the Task Manager - it reported an error while trying to start the Manager
3.Disk Defragmenter problems - which I've discussed on this Forum :-
http://forums.whatth...ity_t83994.html
I used the System Restore Utility and restored my system to a previous date(before inserting the Pen-Drive)..
Problems 1 & 2 were solved BUT problem 3 persists...
If any new problems occur, I shall mention them.
I am also pasting the contents of the HJT Logfile for ur reference...
