This has been an irregular occurance lately on my PC. One day after playing a game, I got a notification that my win10 security needed to be reactivated. I tried to open it, but was painfully slow to load, and I also tried opening Chrome to find a solution, and found that loading any webpages took ages. I did a virus scan wit AVG and Malwarebytes, and found no malware, and after a PC restart everything was running fine again. Fast foward to a few weeks later and same thing happens again, except win10 security didn't turn off so I restarted my PC and everything was fine again. Fast foward again to today and the same thing happened, except that Malwarebytes now scans much faster than normal. Normally it takes 10 minutes to do a bacis scan, but it only took 4 minutes today.
Might I be the victim of malware or is win10 just being garbage? There is also no abnormally high disk and cpu usage.
