Please tell us which file is reported as a virus, the name of the
virus and the name of the anti-virus software that has detected it.
Otherwise, we cannot do anything on such as generic alert as your
initial e-mail message. If you go through the dev mailing list
archive, you'll surely notice that the file jmsoutlookaddrbook.dll
used to be detected as a virus by multiple anti-virus programs but we
worked with their developers and pretty much all of them confirmed
that the problem was in their software and took measures to no longer
report our file as a virus.
