High CPU on Windows 11 System (Ntoskrnl) due to Bitdefender

Beart

For a few weeks I have suffered very high CPU usage on a new HP laptop i5 11th Generation running Windows 11. The system process (ntoskrnl) was causing this high CPU usage. It also drained the battery from 100% till empty in 30 minutes. The first 2 months it was running fine.

Finally found that after uninstalling Bitdefender the CPU went back to normal. Although the processes of Bitdefender seems not be using high CPU in the task manager. Can you please tell me if this a problem currently?
