Bit Defender Scan is killing my CPU is this normal?

Sk001

I'm getting very high CPU usage when I run a scan, it fluctuates but my PC is overheating and blue screening as a result. CPU gets to 99c.

CPU: 12th Gen Intel(R) Core(TM) i9-12900K  3.20 GHz

I had thought this was a problem with the hardware so I just took the whole thing apart, dusted, reapplied thermal paste, runs fine...until I try and scan.

Any tips?

Hello.

Here is a screenshot from my laptop's task manager, while running Full System Scan in the background:

Laptop: Asus X551CA

Purchased: April 2014

Specs: Intel Core i3-3217U 1.8GHz, Intel HD Graphics 4000, 4GB DDR3

Hardware change: November 2018, 500GB HDD -> 120GB SATA-III SSD

OS: Windows 10 Pro 22H2 64-bit with the latest updates installed

But, must say that in my case it is pretty normal, since "Scan task priority" for System Scan and Quick Scan is set to "High", which takes much more resources (CPU, RAM, disk, power) than "Low" and "Auto".

Open your Bitdefender program, go to Protection -> Antivirus -> Open -> Scans -> System Scan, click on the three dots ••• button on the right next to System Scan, click on "Edit", change the "Scan task priority" from "Auto" (default is "Auto") or "High" to "Low", click "Next" and "Save".

Also, do the same steps for "Quick Scan", change the "Scan task priority" from "Auto" (default is "Auto") or "High" to "Low".

If that didn't solve the issue, do the steps below.

-- STEP 1 --

Repair Bitdefender, by following these steps:
