This article is from the Viruses and the Mac FAQ, by David Harley D.Harley@icrf.icnet.uk with numerous contributions by others.
Many major vendors have a virus information database online on
their Web sites. Symantec (www.symantec.com), Network Associates
(www.nai.com), Sophos (www.sophos.com) and Dr. Solomon's
(www.drsolomon.com) include Macintosh virus information.
Precise URLs tend to come and go, but you might like to try the
Symantec Antivirus Research Center
Virus Encyclopedia based on Project VGrep: huge, and now has a
search engine. Probably the most complete [SL]. But not always the
most accurate [DH]. ;-)
