I just got an ISP wide alert from my Internet Provider Planet Internet who are obviously concerned about a new outbreak of the MyDoom worm, MyDoom.M
A new variant of MyDoom, MyDoom.M is currently spreading fast through users systems using the typical mailworm behavior by searching (Google, Lycos, Yahoo en Altavista) for e-mail adresses of possible victims. The mails are then sent using a fake email address with an attachment. The most popular used subjects are: ´error´, ´Message could not be delivered´ and ´Mail System Error - Returned Mail´. As always you shouldn't open attachments unless you know who sent it and you can verify the file type.
We recommend members to download the removal tool from Symantec (if only to check if the infection is already present).
