Error messages after boot scan 42125, 42139, 42145

What are these errors and how can they be fixed?

The two first one are related to corrupt archive, usually a message avast give if it can not unpack and scan a compressed archive for whatever reason (there can be many) the last one is not on the list i found

Any special reason why you run a boot scan?

Just as a precaution. I’m very proactive when it comes to virus protection. Are these errors correctable or deletable? Thanks for responding to my question.

Boot scan does not give any better detection, it is a special feature meant to be used if you have problems removing a malware and not meant to be used as a regular scanner

Are these errors correctable or deletable?
Do you get them if you run a normal full scan?
