Bagle/Beagle Variant Includes Source Code
NASAdude writes "Sunday brought a lot of fireworks... and the release of two new Bagle/Beagle variants. One of the variants includes a copy of its source code as an attachment as it spreads via email. It is expected the inclusion of the source will result in numerous variants.
It's been dubbed Beagle.Y and Beagle.Z by Symantec and Bagle.ad and Bagle.ae by McAfee.
ZDNet ran a story that covers these new variants."
There have been several "anti-virus viruses" that didn't quite work, and ended up being a major pain to deal with.
