Latest Bagle and MyDoom worms on the loose
Bagle.AI and MyDoom.N are both so-called "mass mailing" worms that use a built-in SMTP (Simple Mail Transfer Protocol) engine that sends e-mail messages carrying worm-infected file attachments from computer to computer on the internet, both using faked (or "spoofed") sender addresses, anti-virus companies said.
The worm variants are just the latest in a string of virus releases in recent days that have anti-virus software companies scrambling to keep their customers protected.
W32.Bagle.AI first appeared Monday and is rated a "medium" threat by McAfee's Antivirus Research Team, citing reports of the virus from customers. McAfee rated MyDoom.N a "low" threat, whereas Computer Associates International noted the prevalence and destructiveness of the worm.
