Subject: [avast! heuristic]

I can’t receive mails (outlook express) with file extension .mht

How can i disable this option - [avast! heuristic] -in free avast?

do you get a warning from avast?

if you disable avast mail shield…does it work then ?

I think you will find this is a restriction in OE security settings, it has a pathetic security measure to block what it considers dangerous attachments, it even included .zip in that stupid rule. I switched that off many years ago before I made the switch to thunderbird.
