Winmail.dat file being removed

[MRM4]

I understand some viruses will be imbedded in a winmail.dat file. Unfortunately for us, some of out clients are sending us emails with important information within those files that are attached. But those attachments are being removed. I assume Avast is what is doing this. Is there a setting somewhere to allow those files to come through? We are using Avast Pro. Thanks.

turn off mail shield ......

i suggest you upload and test those attachments at one of these places before you open and run them .....
avast may be correct in its detection     lots of malware come with mail, or the attachment come from a infected machine

which mail client do you use ?
some programs like MS Outlook block some file types by default. For Outlook I use the freeware add-on attachment options
