Can you attach any screenshots of the scan results or the detection alert you got?
It seems like This file was created or detected during the sandboxed execution of the 2 files that were flagged heavily on VT.Did avast detect the file you posted results for? Any screenshots?
I didn't keep any screenshots. However here is a screenshot of my virus chest.
Something of note from that picture: Those files were last changed on 12/9/2016. On the previous version of Avast, these files never showed as flagged. I update often, and scan often. These files had been scanned with the previous version of avast without any issues.
Also, I'm on Version 17.1.2286 (build 17.3394.42) and using Virus Def 170222-3.
