Avast Unable to Scan some files

I just ran a complete system scan with Avast Free Antivirus 2015.

At the end of the Scan there was a message to the effect that “Some Files Could Not Be Scanned” and it listed several files.

I am a computer novice so I wanted to ask if someone could tell me in Layman’s terms what I should do to scan these files to be certain they are not infected.

The scan results give names to these files but I have no idea where to find them and am afraid if I did find them I would in my ignorance do damage to my laptop if I alter them.

Thank you in advance for your assistance.

How do I handle files that avast! can’t scan? https://blog.avast.com/2014/02/28/how-do-i-handle-files-that-avast-cant-scan/
