Who is working on the mapping of various virus names?
Sometimes e.g. ClamWin finds a virus that has a different name fhan the other AV vendors name it later.
Go to http://www.nfllab.com/projects/cvnr/ or:
http://www.rainingfrogs.co.uk/ or the Dutch site:
http://viruspool.vanderkooij.org/ if in doubt.
