GAV & ClamAV

Do you have a virus that is not blocked by GAV.
On the ClamAV website (http://www.clamav.net/) you can submit your sample (http://cgi.clamav.net/sendvirus.cgi) so one of the 'virus database maintainers' of the ClamAV project can make a anti-virus for it.
The great benefit of submitting your sample to ClamAV is that you help out your fellow GAV/ClamAV users by doing so.
