Win32.Swen.a is a mass-mailing worm which employs multiple propagation
methods to spread. The worm may appear to be a legitimate message from
Microsoft. All users must note that Microsoft will never send updates
and paths via email.
The worm attempts to open itself automatically when received via email
by using the I-Frame exploit. eSafe Gateway and eSafe Mail customers are
proactively protected from this exploit and therefore the worm will not
be able to self-execute on protected machines.
Do NOT run (or download) the attachment!
