1-does choosing “speed up scanning by using the persistent cache” reduce thoroughness?

2-does choosing “store data about scanned files in the persistent cache” increase thoroughness?

i’m a bit confused,does choosing second option also speed up future scans?
because it says: “turning this option on will slow down the scan”.

also,how come there aren’t such options for boot scan?

Both options increase scanning speed in an intelligent way, without decreasing the protection, though, without reducing the thoroughness.

ok i get it now,that makes sense,thx guys.

You’re welcome.
