Can someone help me remove viruses from my computer? - removing computer viruses

My computer is infected with the virus. Change your background, my hand, it seems familiar pop-ups, downloads of programs without me. I use Norton Anti-virus change to remedy this problem, but not a bit. I think that happens because I said yesterday the program to see was downloading videos on the Internet, I think X was active or something. Can someone help me remove this virus and restore my computer virus?
