full scan

I am new to Avast and after completing my first scan I have a question. The result showed that some files could not be scanned. messages said: error archive password protected and the other said; error the system cannot find the path (3)

Can anyone explain these messages to me? I just read the faq and found many comments in regard to my questions. Now I wonder if I should take any actions as offered by avast. modify, delete, move to chest etc?

Thanks

Don’t worry. These are messages of scanning issues and not infections.
Some archive are password protected by the software manufactures. It’s normal.
Some temporary files could be deleted from the beginning of the scanning to the end. So can’t be found. It’s normal.
