Well, it happened again. A new virus showed up and Disinfectant was promptly updated by its erstwhile author, John Norstad (who at this point might well be elected King if the Macintosh community was voting). Disinfectant 2.3 has a few minor changes from the previous version. Most notable is support for finding and eradicating yet another version of MDEF, called MDEF C. Like the others, it appeared first in Ithaca. The only other change to Disinfectant is a fix that enables the program to detect a variant of the ANTI A virus that version 2.2 did not detect correctly.
One quick note - if viruses appear near you before the virus tools are updated to deal with them, we recommend using a combination of the latest versions of GateKeeper and GateKeeper Aid. Both are free and available from many online sources. Some of the commercial utilities detect unknown viruses as well, but we don't recommend them as wholeheartedly.
