ClamWin uses the same database as ClamAV (clamav.net).

Please scan the suspicious file online first. There is a good free service provided by www.virustotal.com. Virustotal will scan your files with different scanners, so it is easy to judge if the file is a false positive or really a virus.

If you feel that you found a virus that is recognised by ClamWin or a false positive, you can report it using the on-line form at cgi.clamav.net/sendvirus.cgi. Please make sure that you have updated your database to the latest version before using this form.
