Not sure if I'm infected or not

Recently, my cursor has been moving around my screen by itself and I read about what could cause it. Interference, needing to update a driver, virus, etc. I know that it's not my wireless mouse causing the problem. I took the battery out while it was doing it and it kept up. I updated the driver for my touchpad and so far it hasn't done anything. However, I'd kind of like to just make sure I'm not infected. I very well could have something and it not be related to the mouse thing. Who knows. So yes, could you please help me out?

Also, maybe suggest to me a good free anti virus program? I use to have Norton but my trial expired and I can't afford to go out and spend the money on a new program right now.
