Critical Process Died

Very recently, my laptop started getting random BSOD's, all with the error "Critical Process Died". I first suspected that it was due to my undervolt. My laptop has been undervolted for almost a year with -90mV on the core and cache and has never crashed on me before. I reverted back to the stock voltages but it still crashes. I tried to run Malwarebytes and it found 20 infected files, most of which were Trojans (I am very careful when surfing the web, this is my first encounter with malware in quite some time). After scanning with other programs like Bitdefender, AdwCleaner, and SUPERAntiSpyware, the problem still remains. Please help me.

Hi,

Code:

0x000000EF:    CRITICAL_PROCESS_DIED (29.06.2017 06:52:19) [Windows 10] 
 
CAUSED BY:     svchost.exe    
               atc.sys [6.06.2017]   
 
PROCESS:       svchost.exe 
 

============================================================================================================== 
 
 
0x000000EF:    CRITICAL_PROCESS_DIED (29.06.2017 03:20:42) [Windows 10] 
 
CAUSED BY:     svchost.exe    
               atc.sys [6.06.2017]   
 
PROCESS:       svchost.exe

Both bsod dumps show atc.sys as cause. Its part of Bitdefender:
What is atc.sys?

U should remove Bitdefender via uninstall tool:

How to uninstall Bitdefender 2015

After u removed it you should repair windows file system:

1. Open an elevated command prompt.
2. In the elevated command prompt, type these five commands below, and press Enter:

dism /Online /NoRestart /Cleanup-Image /RestoreHealth
dism /Online /NoRestart /Cleanup-Image /StartComponentCleanup
sfc /scannow
chkdsk C: /F /R /X
fsutil dirty set C:

SFC:
The SFC command scans the integrity of all protected system files and replaces incorrect versions with correct Microsoft versions.
DISM:
If a Windows image becomes unserviceable, you can use the Deployment Imaging and Servicing Management (DISM) tool to update the files and correct the problem.
For example, you would use DISM to fix Windows component store corruption when a sfc /scannow command is unable to repair corrupted or modified system files because the component store (source) is corrupted. SFC should be able to repair the files afterwards.
CHKDSK:
Checking your drives for errors every once in a while can help fix some performance issues. Drive errors can usually be caused by bad sectors, improper shutdowns, bad software, corruption, physical damage, etc...
