Are you referring to the joshi BSV virus? Zaggy is right in saying you won't find it here. Not to mention that the virus is 10 years old and doesn't break any new ground in virus writing. If your interested in researching for this stuff for security reasons, you might want to do a search on a P2P network for Mark Ludwig's "Black Book of computer viruses." You will NOT find any virus howto or sources on this site.
