after scan, large memory occupied

[henri44]

hi,
after a quick scan, I found a large memory occupied,
AvastSvc.exe:
after starting the computer                  → 25828 K
during fast scan                                    → 89428 K
30 minutes after fast scan completed   → 72160 K   

Is this normal?
Thank you for your answers

measurement made with Process Explorer v 15 40

weird after a standby, AvastScv is back to normal
