--> What is it?

W32/Mydoom.o@MM is a Medium-On-Watch risk mass-mailing worm
that tries to open a hacker backdoor on your PC. Often
pretending to be a bounced email alert, the worm arrives
inside an attachment then spreads by sending itself to stolen
contacts and via peer-to-peer programs.

--> What should I look for?

BODY: Example: We have received reports that your account was used to
