Yes - just got confirmation that Quick Heal is currently installed. (It's not my computer, I look after it for a non-tech friend). Are you suggesting that it might be the cause of the problem? I prefer avast myself.
First time I've encountered something CCleaner couldn't fix.
Got this message when running the registry cleaner:
Application Paths Issue MachInfo.exe - C:\DOCUME~1\Glenda\LOCALS~1\Temp\machinfo.exe HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\MachInfo.exe
Any clues as to what to do about it?
