I think i could have a virus, Malwarebytes shows nothing although i do not have premium. I ran a scan there was nothing but when I run a windows defender offline scan it boots back to windows after stopping at 55000 files at 91%. In the event viewer I am getting 5007s and a 2030. I need to get to the bottom of whether or not my performance issues are coming from a virus before I move on to other things.
