Hello alanrf, Hello Igor,
thanks for your responses. Unfortunately, I was not able to get my mails back yet.
I tried to extract the file. Avast renamed it to: PartNo_0#1182120384
Its size is only 96.172 KB. My Inbox was a lot bigger than that...
In addition, I cannot open the file with any of my programs.
Can you give me another hint, what I should do?
I kind of lost trust to avast, since it moved my whole inbox-folder without me doing anything. Have you heard of this problem before?
Thanks again & have a nice day,
euphemos
