Full scan

Used : 89 GB/ 458 GB

Scan MB = 91136MB.
Scan time = 4800s.

The calculated (average) performance is, SSD AV full scan : 19 MB/s.

Thankful and yet confused.

By changing the priority of the full scan from Background to Normal the execution time decreases by more than 35 minutes.
As when I run the full scan I don’t use the laptop I didn’t think that the Background priority could penalize the execution time so much.

The Windows specialists of the forum surely have an explanation.
