W500 Issues. Cursor movement, Web page aborts, uncontrolled scrolling, random page loading

Question

Dear Reader and / or Correspondent,
I am experiencing issues with my Lenovo laptop computer and my Microsoft Windows Vista operating system. My issues’ are many and they all revolve around the phenomenon of either a ‘floating’ cursor that wanders across the screen; or, ‘jumping’ pages or windows that appear unasked for and uncontrolled.
The cursor moves across the screen even when it is not controlled by the user. It moves like it had a will of its own. Sometime sit refuses to move at all. But if a enough time is allowed it will resume submitting to the user’s direction. On other occasions, it leaps about the screen as though it had a mind of its own. If left on its own it will wander about the surface of my desktop or inside a lit or activated Window.
Coincidently, the windows or the ‘screens’ or the ‘pages’ displayed on the LCD panel of my laptop will randomly change their content or size. If I am surfing the Internet the pages or the screens may float or leap to or transition to a prior screen iteration or to a completely new screen or to a web page that I last visited several week prior all of the
This erratic behavior began after I installed all of the recommended software updates, improvements and security downloads from Microsoft and Lenovo last week. I was acting in response to their instructions to upgrade my software defenses following the release of the STUXNET malware.
Since this phenomenon began my last week I have been unable to use my Lenovo laptop in a professional and relaxed manner. It is constantly forcing me to correct its random maneuvers and unpredictable behavior. It is a great burden and it is very inconvenient.
By the way, this unpredictable and troubling behavior occurs when I am composing correspondence, visiting web sites and playing computer games. Just typing a simple email is a challenge because of this wayward behavior. I never know where the cursor will travel to on my laptop’s screen, when it will move and how often it will occur.
Suffice it for me to say that: “… it’s a real pain in the butt.”
Can any of you recommend a solution to this problem? Have you ever experienced anything like this issue? Is it a software issue? Or, is it a conflict between two or more software applications? Does the problem occur because a file has been damaged? Is a piece of hardware causing this error? Have any of you experienced a similar set of challenges?
Coincidentally with this cursor error I have lost the ability to access my email account. My account exists and the email is in the account. But my laptop will not link to the mail servers (Yahoo and ATT.net). My Outlooklink to my email account does not work either.
My laptop is a LENOVO W500 ThinkPad.
My operating system is a Microsoft Vista Business 64, Service Pack 2 operating system.
My laptop is configured as follows:
CPU: T9400 @ 2.53 MHz Core2 Duo Centrinos
Video card: ATI FirePro v.5700 with 512 MB
Memory: DDR3 4GB.
Mice: HID and IBM ThinkPad Ultranav Trackpoint and Touchpad.

 COuld you please advise me what the possible source or cause of thee issues is ?

HI, Ed and ~Bee —
Ed, a tiny complement — maybe — to ~Bee's successful solution...
I also use both an Apple Bluetooth and an older cordless LogiTech mouse. I keep them separated — except when I need to use the latter to help "re-connect" my Bluetooth mouse. I've noticed that if I forget and leave them near each other, my cursor begins to "skitter" something awful! Moving the LogiTech mouse a few feet away solves the problem.
