Last night I updated my Norton Antivirus (NAV) virus definitions. Shortly after that, a window from NAV pop-up and notify that there is a threat. The threat is from tuvussr.dll (C:/Windows/system32/tuvussr.dll). NAV couldn't delete the file because (after I saw from Tuneup Utilities Process Manager, the file was opened by winlogon.exe). To delete the tuvussr.dll, first (based on my experience) we need to terminate the winlogon.exe. But, terminate winlogon.exe means restart the PC.
My question, what do I have to do to stop winlogon.exe without restarting (so I can delete the tuvussr.dll)? Or, is there anything I can do to remove the tuvussr.dll file?
Thankyou for answering my question.
