That is why you should implement content blocking at your e-mail server.
There is absolutely no reason to allow .scr files to go around. If you had
this blocked, it would stop MiMail-I without AV updates.
Also, note that this attachment has double extension, which should also be
automatically blocked.

You can check unsafe extensions list at Microsoft's Web site:
