High CPU usage during scans

Nunzio77

HI,
I'm doing a complete scan of the PC but maybe the percentage of CPU usage during the scan is a bit too high also because there are two processes running with a high CPU percentage. Wouldn't just one be enough?
Why does "bdservicehost" also use a lot of CPU since "Bitdefender Antivirus Scanner"

is running?
Optimizing processes would reduce CPU usage and consequently improve PC performance during scans.

The % of CPU usage reaches peaks of around 60% - 70%.
