A couple of months ago I was hit by the "Klez" virus because a family member opened an attachement in Outlook. I had F-Prot 3.12 running, but "Klez" simply shut it down, and ruined the executable. Which antivirus programs can handle attempts by virii to shut them down ('cause F-Prot certainly cannot)? I mean, they are not to much use if that can happen. Furthermore, is it possible to use Windows 2000 permissions to protect Antivirus applications? Suggestions are welcome.
