On Windows what file extensions do you have to look out for concerning viruses/worms? I ask because I'm wondering if there's a point in scanning .cfm files.

A file extension is just an arbitrary label. – iglvzx Jun 11 '12 at 21:54

Any exploitable executable could become a vector for infection. Since you can't really know ahead of time which apps are exploitable...

Because of stack overflow and such bugs in the software, any data file with a buggy data reader can be an attack vector. It does not need to be an executable.

This goes for image files, font files, etc.

The difficulty is that viruses/worms may make use of files with all sorts of extensions, either just as a place to hide themselves, or as a vector for infection. On the server side, there are certainly cases of infections hiding within files with .cfm extensions.
