Antivirus software companies are warning customers about a new e-mail worm that targets unpatched Microsoft Windows machines with either of two recently disclosed software vulnerabilities.

The new worm, known as both "Plexus" and "Explet.A," was first detected on Wednesday and spreads by exploiting Windows machines with vulnerabilities used by two recent worms, Sasser and Blaster, according to alerts. Network Associates' McAfee Antivirus Emergency Response Team and Symantec both say the new worm does not pose a serious threat, but issued software updates to detect it.
