Yawn I’m Back! Yawn
The error displayed (Currently) is a Registry Error. Something is attempting to set a value in a protected key, and M$ doesn’t like it. Hence Access is Denied. I’m guessing you’re not running an Admin account, or a system inside a domain. This shouldn’t be causing a shutdown…
No, it’s not almost always malicious. The School systems I have access to have; all forms of Reg Access (Under Local Machine…) are actively blocked to Student access (And teacher, except Tech Teachers).
What would be more interesting to see is the BSOD crash reports, as well has an FRST, aswMBR, and MBAM Scan.
FRST/aswMBR/MBAM instructions can be found @ https://forum.avast.com/index.php?topic=53253.0
BSOD Crash reports (*.dmp) can be located @ C:\Windows\MiniDump.
Post All crash reports to www.wikisend.com (ZIP all of them, and upload it as CrashDump.zip). Post the D/L link here to the tech’s can take a look. Depending on when you respond, and where people live (I see we have a new one :-)). An answer might take a several hours.
Edit: Fixed my trashy Shieac (English and French…) lol
Note: Typing an answer after just finishing Pre-Calc 12A homework isn’t a good idea D:
