USB Thumb Drive Scanning
« on: December 21, 2022, 04:00:55 PM »
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".

"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.
