Avast can't get rid of a few viruses

Okay I have the free avast system for cleaning my system. However, I did a scan a couple of weeks back and I picked up a few viruses, but when I tried to delete them, they said they were password blocked with the error code 42056. Is there anyway to get rid of these?

they said they were password blocked with the error code 42056.
i guess avast said it could not scan the file(s) because they where password protected ? this is the most frequently asked question in the forum, so plenty info if you search

if that is what avast said, then it is not a detection … just a scan error message
avast is a antivirus program and will only take action on infected file(s)

How do I handle files that avast! can’t scan?

they may be file(s) needed .... what is the location, full file path
