I have a file C:\$WINDOWS.~Q\DATA\Windows\System32\drivers\sfi.dat which cannot be removed.
It was created after updating from Vista to Windows 7.
I find reports on the internet that this file was originally coming from Comodo virus protection.
I have been attempting all availabe suggestions on the internet, like removing in safe mode, using unlocker, stopping explorer and then delete in a command box and many more options, but all in vain.
I also tried disk cleanup and now run out of options.
Is there anyone out there who has suggestions ?
I would be gratefull.

Hallo mvandinther,

Are you currently using CIS?
AFAIK sfi.dat is needed for Comodo Antrivirus Stateful File Inspection and its deletion of  appear to be prevented by CIS though it can be removed after CIS uninstallation.
