So I turned off my "use a proxy server" option under LAN settings in win 7 a while back. It helps with the downloads. But I went back to it and it was checked. I unchecked it and a duplicate window pops up, checks the same setting, then closes. After several attempts I managed to hit the X to close it but then everything freezed. Still had audio but video was frozen for a good 15 seconds. I had to three finger salute (ctrl alt del) but all my displays just went black for 10 seconds at least. I got to the task manager but everything was super laggy until after those windows closed. Kinda freaked out. No viruses that I can tell from malwarebytes. Any ideas/fixes?
