Assuming you have APFS TM disk: It would mess up restore if it could remove it. But it can't! TM snapshots are read-only.
Yes my TM External HD is APFS Formatted and Encrypted. I'll keep it off the scan list. If something ever goes bad on the iMac that requires restore, I can always run VirusBarrier again to clean it up. Thanks for the info.
