Clean-up begins from MyDoom virus

Computer technicians worked Tuesday to disinfect thousands of computers worldwide struck by the MyDoom virus a day earlier, the Washington Post said.
A new variation of the malicious code appeared early Monday, and soon after, the Google, Yahoo, Lycos and AltaVista search engines were overwhelmed for as long as five hours.
The virus circulates the Web disguised as an e-mail with various subject lines, such as "Mail System Error," or "Undeliverable Mail."
Many messages purported to come from the user's corporate e-mail or Internet service provider: "Your e-mail account was used to send a large amount of junk mail messages during this week," read one message bearing the malicious software. "We suspect that your computer was compromised and now contains a trojan proxy server."
The computer would only be infected if the recipient clicked to open the attachment.
The original version of MyDoom in January attacked the Web site of a Utah technology company called SCO Group Inc., which has angered many programmers by filing lawsuits claiming it owns intellectual property related to the free, open-source operating system Linux.
