Deep Scan Run-time reduced from 18 minutes to 8 minutes

Hi Christine.
We'd like to inform that the later scans will take less time to complete because the time taken to analyze the files for the first time is higher.
I see that every file is scanned on your PC on both occasions and I assure everything is working fine.

I have AVG Internet Security. I run Deep Scan almost daily. I noticed that the run-time has reduced significantly by 10 minutes. It was 18 minutes on 31st July, 8 minutes on 3rd August and 8 minutes on 4th August. The number of files scanned seems to be about the same each time i.e. 479,000+ files.

I read somewhere on the internet that if an anti-virus scan finishes too quickly, the PC could be infected with a virus. Please tell me if there is a problem.

My virus definitions are up to date. Release date was 5 August 2020 00:30 (ver. 200804-8)
My application is up to date. Release date was 30 July 2020 08:24 (ver. 20.6.3135 - build 20.6.5495.587)

Below are from my Deep Scan report:
