My background disappeared and was replaced with a blue screen with a blue and yellow box in the middle. I was just on the computer, downloading a torrent from a trusted site when a pop up appeared, asking for access to the computer. Thinking it was because of the torrent program i was using, i granted it access once. It said it was some unknown program and i think it caused my weird background. What exactly happened? Also, this is my dad's desktop, so i don't want him to know what i did or else i'm dead. I'm not very computer savvy also, so please give me simple and clear instructions on how to fix everything. Please help me!!!!!!!
