I've very recently formatted my computer because I experienced lag and some network issues, like being blocked by some services utilizing Cloudflare. The windows would also occasionally report weather conditions and etc from a different location than my city. But now it's a fresh win 11, so it seems fairly responsive and light to the touch, but I'm not sure if everything is still completely fine. I ran MSERT and it suspected one infection mid-scan, although afterwards it reported the system as clean. When I open task manager, the CPU usage is at around 50% and then drops down to 2-4%. Empty paranoia I should suppose, but the following does worry me, I've only had the fresh system for around 12 hours, yet there's already 8300 events in security logs of the event viewer consisting of for logons and special logons, timestamped even when I'm particularly using the computer and it's just sitting around. This in particular worries me because I am the sole user of the computer and the network, at least supposedly. I ran the Farbar and Malwarebytes scan.
