We block all executables (.exe, .scr, .bat, .com, .dll), Windows Clipboard Files and McAfee Anti-Virus Definitions (DAT 
> files).

Blocked files are replaced with a file that contains a ticket number that they can use to request the help desk recover 
the blocked file.  We rarely get any requests for this.
