Something got detected in my firefox folder.

Just switched back to the beta and my full scan results turned out to detect 3 things in firefox folder,they were the same files with same hashes,so I moved them to chest and scanned them at VT:

avast says there is something called “anything.vbs” inside the file that makes it look bad.I havent suffered any browsing problems or anything with my PC.Actually MBAM Pro has been on this pc all the time I was away from avast.

Anyone has the idea what it is?
