Remote Access Trojan virus?

Recently my computer has been bogged down, and when I have a search bar activated (When you can type in it) someone on another end is typing into it (Not random letters, real words and phrases). Also, any flash videos are randomly paused, even when fully buffered. I have a firewall, AVG Internet Security, and Spybot S&D. Nothing. Any help would be very appreciated, right now the computer is disconnected from the internet.

Is this the same computer?
