Hi Michael, If it was a problem with malware or something, I'd expect the same thing to happen on Ethernet as well, not just on Wifi. Did you update your drivers? And did you turn off hardwareupdates in Windows 10? About 1 minute to turn the system on or off is quite long indeed, especially since you have an SSD in there. Is this also related to the Wifi connection or does that happen all the time? In the screenshots I dont see anything that stands out to me (but I have to admit my Polish is a bit rusty :P), except for the fact that you are running 2 anti virus. Its best to run only 1 at a time since they might interfere with eachother and cause problems / slow the system down. Besides using a single anti-virus I'd suggest doing a scan against malware with Malware bytes anti-malware (I run a manual scan with the free version every once in a while).
