That signature has been in the database since Oct 20, 2017 and is a hash signature, so there's little chance of it being an FP.

Seems to me that this is a false positive.

I sent a copy of the file to other vendors to double check it and they reported it was not malware.

I have submitted false positives to ClamAV before and never received an update on them:

What do others do when they get ClamAV false positives?
Thanks,
