I was browsing a website a few days ago and then my ad blocker said “This website is trying to use your computer for Bitcoin Mining, press cancel to stop” so i pressed cancel and left the website. 1 day later my computer was really slow, my CPU was 100% and GPU was 100%. I ran 3 different antiviruses and none of them came up with anything. This is frustrating since playing games is unplayable with constant stutter. Please help!
