Today i went on my computer and i randomly had all sorts of issues. I ran malawarebytes and removed everything. When i restarted i could open for example firefox but after 5 minutes i could not open any other program, not just browsers. Once i click to open something it would show the loading circle for a couple of seconds and then nothing would happen. If i click refresh on my desktop the loading circle pops up and never goes away. My background gets like a shade of white over it and i cant even press my start menu. If i try to go to task manager the screen goes black and says "failure to display security and shut down options when ctl+alt+del was pressed. I tried to restore back to several dates but still no change. Im am not sure what this is or even if it is a virus, but some feedback would be greatly appreciated.
