My Memory Scan found 3 mbmamservice.exe as a threat. Why?

was this a custom scan and you have selected “scan memory” ?

Thanx for asking. Yes it was…Oh, one more thing: Using Acronis backup, I restored my machine to stage a few days back, and guest what…this time that very same scan found nothing.

When using Custom scan, don`t select scan memory, or better use the default quick/full scan with default settings
avast team have made these scan bc they know what is best for the normal user, they should know bc they play with malware 24/7

Thanx for your help. I really do not understand why is memory scan there. When I buy something I expect ALL functions will have reason to be there, and will works as designed …and constantly. Well I’m glad I did not let Avast to upgrade to last version…seeing all those troubles in forum…
