Having two active AV scanners will not help- it will only cause conflicts and instability.

Have you tried a boot time scan with avast!? Right click the scanner screen, select ‘schedule a boot time scan’ and reboot when requested.

Try a scan with AVG in Safe Mode.

(There’s no guarantee that either AV will work properly with another present.)

Try a few online scans in Safe Mode with Networking.
