constantly moving cursor

When I open a webpage the cursor keeps moving the page up and down. I can try to scroll down put the page will jump back up. I can try and go back to the top but the page will then go to the bottom.
I have tried system restore and took it back hours and then days- that did not work.
I ran AVG and AD-Aware- not sure if I should have anything else. I had Firefox but now cant use it as, as soon as I click on "file" "edit" or anything the drop down menus just go "mad" and all open and close in rapid succession.
