Hi everybody
i am paranoid person about security. from few days i shared a post about Discord distributing Trojan
from that day my paranoia has increased, i uninstalled Discord used Revo uninstaller to completely remove any Discord traces or registry keys.
but i notice that my Laptop shutdown some times without any notification although it is connected to the charger, i checked the Event viewer (for first time in my life ) to try to understand the changes in my OS but i noticed changes at the kernel level as in the screen shot
is it something suspicious or just may be power problems i want your advise
Note:
  1. i am pausing Windows updates until 31/10 so it is not windows update reboot or shutdown
  2. i scanned with Emsi/NPE/KAV/Zamana/Malwarebyte nothing caught

If you can rule out malware and other hardware like disk, only other time besides power supply I know is thermal-related. Like your vents are clogged and/or a fan is not rotating properly. Maybe you can check temperatures at load with HWINFO64 or HWMonitor.

I did a search, you can find the shutdown logs in Event Viewer. Your screenshot above doesn't indicate anything of relevance.

 
In the past, the sudden shutdown I experienced was due to power supply hardware problems and lack of heat dissipation.
If you are shutting down with a heavy CPU load, such as when editing movies or playing games, you are likely to have a thermal problem.
 
I agree with show-zi. Make sure your CPU heatsink is not full of dust. Does the fan spin up a lot and does the laptop feel hot? What does shutdown mean? Just turn off with no message? If so, I would suspect either hardware issues or a dirty CPU heatsink.
Yes shutdown without warning and some times the span of fan increase suddenly
