My brother has a lenovo laptop running windows 7. When he's working or surfing the computer seems to left click on its own. So if he's working on a word document and the pointer is on the top of the page the computer does a phantom left click and the insertion point moves to where the pointer was. Basically it's left clicking on it's own. I uninstalled the mouse drivers and reinstalled them but it's still doing it. Could this be a virus? We did a virus scan with AVG updated and no result. I really doubt that this is a hardware issue -it rarely is. Any ideas????
