The mouse or touch pad is a very important piece of hardware that is used to navigate folders, launch programs and access the right or left-click options. Sometimes users may face issues where the mouse or touch pad starts moving around erratically, and merely pointing the cursor on an icon causes the program to launch automatically. This issue is also known as automatic click issue. The most common cause of this problem is an outdated driver. The solution lies in updating the required driver by accessing it from the menu option concerned.
Mouse or touch-pad acting erratically - automatic clicking issue
This is a very annoying issue; when I was typing on my laptop my cursor would jump around, and putting the mouse pointer over an icon would automatically launch the program without any human intervention. Even after disabling the touch pad of my laptop and plugging in a USB mouse, the problem was still the same.
Right-click on "My Computer" on your desktop
At the top of the window that appears, left-click on the "Hardware" tab
Left-click on the "Device Manager" button
Look down the tree of Device items and left-click on the plus sign (+) to the left of "Mice and other pointing devices"
At this point, under the "Mice and other pointing devices" heading, you should see one listed item (driver) if you're using just your touch-pad or one mouse
Right-click on that driver name - in my case it's "Snaptics PS/2..."
From the menu that appears when you right-click on the mouse driver, choose "Update driver" by left-clicking on it.
Follow the update instructions
That's it. After you've updated your driver, reboot.
