I have been using Viruscode 8 for more than 6 months and have not received
even 1 false positive,

But my users are not a very large group and they most likely do not send a
lot of attachments via email.  I have taught them how to transfer files
actually via ftp.

Bonno,

I don't know how much false positives it would produce but I haven't never
heard some customer complaining about it. Until this morning there was not
more then 2 or 3 "Unknown Virus" warnings per day with 13000 processed
messages/day.

But in this case - if I have understand it right - it was very usefull to
have viruscode 8 enabled.
I've seen the first "Unknown virus" message this morning at 09:30 AM. F-prot
has had updates ready 3 hours later. In the meantime there was an average of
10 Bagle.AP infected messages per minute - catched only with viruscode 8.

Until I've discovered what's going on here (the "unknown virus" story) and
adapted the virus.cfg file with appropriate BANNAME's there was a large
number of messages that would be delivered without this setting.

Imagine that the breakout happened at 09:30 GMT+1 So I was already at work.
People in american timezones was at work when AV-companies has had updates
but Mailservers are delivering messages also overnight...

Markus
