I did an eicar test and your sever is blocking viruses and seems correctly configured. Probably a weakness in avast as a guess I will investigate though, can you dropbox or otherwise send me a couple of samples I want to try them here and submit them to avast to see what happens.   You can block all binary attachments using the *simple* virus settings if that's viable for your environment.

Hi,

We have AVAST running on our server.  Also, we have a user who got hacked and who also received more than 50 infected spam emails today - settings are for everything to be delivered to her box with SPAM notation.  ESET discovers each of these viruses.  But AVAST catches nothing.  I’m wondering if it’s just a weakness of AVAST or if for some reason my server is misconfigured.  I’ve included the AVAST portion of the status page in case that can give any clue about what’s going on.  Note: the AVAST Status file age is ALWAYS 0 minutes.

Thank you.

Patrick
