A new computer worm is reeking havoc.
It's being called "My Doom" or "Novarg" by anti-virus companies.
It shows up as an e-mail error message, with a small file attached.
When the file is launched on computers running Microsoft Windows, it can send out one-hundred infected e-mails within thirty-seconds.
The worm was first noticed yesterday and quickly clogged networks with thousands of e-mails.
Infected file attachments include the extensions ".exe," ".scr," ".cmd," ".pif," and ".zip."
If you receive an e-mail from an unfamiliar sender containing one of these extensions, or containing the text... "This message contains unicode characters and has been sent as a binary attachment," delete it immediately.
Anit-virus software can help prevent infection, and Microsoft offers a patch for its outlook e-mail software to warn users before they open some attachments.
