guess what i had it turned off since over a month

still it gives me the error
Then it is not due to System Restore but due to inability of the antivirus software to clean it thoroughly. Do this,
1. Turn OFF system restore option
2. Restart in "Safe mode"
3. Scan entire PC in stealth mode (I suggest Spybot for successfull removal of this worm)
4. Now run HijackThis
5. Check for C:\WINDOWS\tbljqmnj.exe entry in the log report
6. It should not be there. If by chance found, remove that entry.
7. Run Ccleaner
8. Reboot again in Normal mode.
