It would be much faster here, can you either give in indication of what is in these messages or post a screen shot to help pin it down.
No problem, the messages I'm referring to are the red-text-on-yellow-background ones that pile up in the bottom right corner of your screen under the heading "Avast On-access Scanner Message" as virus-infected email gets d/led from the server. Each line details the virus, where it came from etc. If you're unlucky enough to have an email account that gets hit hard, these will come in so fast that the lines start to pile up until they occupy half your screen area. If you right click on them they'll disappear, BTW, but that's not a good solution for my users. They don't want to see anything.
As I said before, the "show detailed information" checkbox is not checked on any of the providers loaded. I do have them all running in silent mode with Yes/Delete/Deny as the default actions in case that helps - I think that's the only thing changed from the default behaviour.
