552 virus found in message

[rhythm]

I work for an ISP and we have been seeing (552 virus found in message) all morning from poeple running symantec and AVG antivirus.

Most poeple can get around this problem by disabling the outgoing mail scaning.

Does anybody have any insight on what is causing this?

Sounds like someone is spreading a Klez worm. More info here :

Well, looks like this was the cause of the problems with our mail server.
