(~Certain versions of Sophos antivirus claim that the files are infected
with with the Momma-B trojan (when they are not), response by Sophos:)

"This is almost certainly a case where the user has downloaded the
standard version of Sophos without the IDE files.

There is an issue with detection of Troj/Momma-B on the standard version
of 3.58 which is resolved with the IDE file which was published on our
website at: http://www.sophos.com/virusinfo/analyses/trojmommab.html on
the 21st of May.
