Mouse causes click action without clicking it.
When I move mouse cursor over any icon it opens that icon.
I am using PC with windows xp3.

Found this online let me know if it helps..

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

Mouse or touch-pad acting erratically - automatic clicking issue
