Hi
you might test your HAVP with EICAR or with "real" viruses.
This german site http: //testvirus.de/de/liste.html gives you some viruses on demand (I made this link not clickable, please remove the blank). Seems to be safe - if you do the right thing.
For those you cannot speak german: Click on each Virus section to "Herunterladen" (Download) and you get a site, where you can download this particular virus in raw, zip etc.
Please make really sure what you are doing !
Regards,
Alexander
PS: ClamAV seems to detect them all with HAVP.
