Yes it was. Some how it recreatet itself or was recreated after Avast moved it into the container.

Since your file was signed by Nvidia Corporation, I suspect that Avast incorrectly reported it as malware. If you like, upload it to virustotal.com to see what the other anti-virus programs say about the file.

Please let us know what you find.

McAfee internet security, recently reported(24-3-15) that Ontology.dll was infected with Trojan: PWS-FBYV!CAEC305B5825 and had infected other files on my PC, it removed the infected files and left a link to the Trojan in McAfee's database which when clicked on gave no information whatsoever about this Trojan.

I think some anti-virus companies leave some false reports in their databases to catch other anti-virus companies that are using/copying their databases without permission.

If in doubt the safe thing to do is to delete NVIDIA nvbackend folders
