I am using my school computer, and I found a virus, so using trusty malware bytes, I got rid of it, then I had to delete the original file, and my lc said I couldn't coz it was open already. So I went into task manager and ended the background task, then I restart and I get a black screen with the top of a box, my cursor and that's it, I can press ctrl alt delete and as soon as I click task manager, it goes back to black screen. The box thingy says "windo..." and all I can do is move it around,, can't even enlarge it. I don't have the windows disk so I can't reinstall windows like that. I don't know what to do. I have school in 2 days. Soz for bad English, I'm typing this on my phone.
