“Antivirus experts have identified new versions of three major e-mail worms and say that a ‘war’ between rival virus writers may be to blame for the rash of outbreaks in recent weeks. New versions of the Mydoom, Netsky, and Bagle have all appeared on the Internet in the last 24 hours. Antivirus researchers have uncovered text messages in two of the worms that suggest a battle is underway between virus writers, antivirus companies say,” Paul Roberts reports for IDG News Service.

Roberts reports, “Examples of Netsky.F, Bagle.K ,and Mydoom.H were isolated on Wednesday, according to antivirus company F-Secure. All three variants resemble their predecessors, which spread in e-mail messages with vague-sounding subjects using infected attachments such as .zip, .exe, or .pif files.
