I need to take a full scan of my USB drive that I have a system image already installed on the drive. I have used a targeted scan and a custom scan & only takes about 5-seconds at most. Scan history shows 5- files and 5-folders with 24.7-GiB tested. I don't believe it tests all that in that length of time. Is it accurate & is there any way to take a full scan? I am using the Free Antivirus Version.

Make sur that in the setting you allow checking for compressed files.
Turn it off again after you finished doing your targeted scan.
-
I cannot seem to find any setting for compressed files. Would there be a chance you could look that up & tell me where I might find it? I do appreciate the help.

Settings > Protections > Virus scans.
Scroll down to "Installers and archives".
Check "Scan all archives".
As Bob says, Turn it off again after you finished doing your targeted scan.

"Scan all archives" was already checked & shows it as recommended setting. I tried turning it off, resetting priority and sensitivity and still scans in about 5-seconds. I believe the thumb drive is okay & so what about if I do a quick format (erase) and then scan again? I don't see how it can check about 24-GiB in 5-seconds.

You could enable 'scan whole files'.
5 seconds doesn't sound unrealistic if it is indeed just 5 files. Avast by default only scans the parts of the files most likely to be affected by viruses etc.
