These 2 files appeared first in 081115-0 and are not marked at all in Virustotal, not even by Avast.
I see that the defs from 081114 are used by VT.

They are both already submitted to virus at avast.com.
It isn’t unusual to not have avast detect on VirusTotal when it does so on your system. VT isn’t able to update the VPS in real time as the user is and this is often the cause.
Remember the point of submitting it to VT is to see what the other scanners find.
