A new variant of the MyDoom worm discovered on Tuesday downloads malware from an MP3-downloading site and a personal Web site, according to security experts, who claim that hackers have compromised these sites by exploiting scripting vulnerabilities in their guestbooks.
Yahoo has announced it will reject messages with certain subject lines to combat delays incurred due to the MyDoom virus.

The Bagle computer virus has almost finished off the alphabet. Virus writers' penchant for modifying the source code for the program has resulted in four new variants--Bagle.Q, Bagle.R, Bagle.S and Bagle.T--in the past two days, antivirus firms said on Thursday.
