Detecting Virus Every Time I Backup

[REDACTED]

I recently started using Carbon Copy Cloner to create a bootable backup of my system drive as well as data backups of several external drives. Every time a backup is performed, 8 files are added to the Virus Chest in Avast and I'm getting a warning. These files have already been deleted from the system drive via Avast, so I don't know how they're being copied each time there's a new backup, or why Avast is recognizing them as a virus. I've attached a screenshot of the virus chest.

Has anyone else encountered this issue?

What does the detection message from avast say .... All info, or post a screenshot

I've attached a screenshot here. It seems to have stopped, although I haven't done anything differently. I'm deleting the files in the virus chest from yesterday, maybe that will trigger it to catch them during the next backup in a few minutes–I'll update.

No, whatever is or is not in the chest has nothing to do with detection. Chest (quarantine ) is just a storage container for malicious files detected

Anyway the detected item on your screenshot  is not dangerous, more annoying
