A friend of mine had me look at his computer and whenever I select an icon by double clicking with the left mouse button it opens up the properties window. Also all of the keyboard buttons don't do what they are suppose too. It's like somebody changed what all of his buttons do. Like the "a" button is the "alt" button and "f' is enter. I can't type at all either because all of those letters don't work but do other functions like I stated above.
Is this a virus that changed the key settings and mouse settings.
