Under both Windows XP SP2 and Windows 2000 SP4, the shell
(explorer.exe) will not execute a file with a ".<space><space>exe"
extension. However, from the command line (cmd.exe) it will execute
it.
However, with this particular worm, it probably will come down to how
Winzip handles the extension, and it doesn't execute it either - it
just uses the Explorer file associations.
It seems that it is quite hard to accidentally execute such a file.
