Just the other day I was using my notebook and my antivirus popped up that I had a trojan, I cant remember the name but it looked pretty bad and I googled it and found that it said the easiest way to fix it would be to reinstall windows.I left it for the time being and since school is just starting back I haven't had much time. Today I came back to it and I cant get it to boot it jus stops at the black screen with the dash in the upper left hand corner.I tried from CD and hard drive.Neither of them will boot they both just stay at that screen.I was wondering if anyone could help me.
