Random PC restart

I was watching a youtube video and all of a sudden windows firewall appeared and said something about a weird file. I closed the window and continued with what I was doing, not knowing what the thing was about. Not 15 seconds later another window popped up and said something about a virtually signed driver and my pc restarted. I couldn't read all the text because it just closed itself after 2 seconds. My pc just turned on and I need to know what this is. After researching a bit I found a few errors in the Even Viewer that appeared at the time when my pc restarted. Here's what the first one says. "Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected." The second one is a warning and it says: A timeout was reached (30000 milliseconds) while waiting for the syshost32 service to connect. The third one is a warning again: Name resolution for the name miodzaki.bit timed out after none of the configured DNS servers responded. The fourth one is an error: A timeout was reached (30000 milliseconds) while waiting for the syshost32 service to connect. After researching some more stuff I found out that a file named syshost.exe is connected to many errors on my pc, including the one that happened before my pc restarted. It's located in C:\Windows\Installer{F5A90208-4BD4-0D6D-2192 and it has almost no info on who made it and things like that. What do you recommend that I do? Should I try to remove this or wait one or two days until I completely reset my system?
