Had any mouse problems lately? I realized a few days ago that my mouse was doing its own thing, going all over the screen and jumping and running, without my intervention. I knew it was not a virus because I did a complete scan and everything was fine. The problem was that my mouse was “dying”. It was very hard to control where I wanted to click and so on. So I decided to change the mouse and - volia! - problem solved. Be aware that there are times when a virus can be the cause of your mouse behaving abnormally, but fortunately for me that was not the case.

Generally a mouse responds to how you move your hand. The speed of the pointer movement can be adjusted in the Mouse settings under Control Panel. So too can the click and double-click speeds. If your mouse has started behaving in a manner that it never used to before, first perform a virus check on your computer. If that checks out okay, buy a new mouse. More often than not it will solve the problem.
