Is this a wireless or an optical mouse?
A. If it is wireless, have you changed the batteries?
B. Is the mouse transmitter located close to the mouse; not obstructed? Try putting the transmitter closer to where the mouse is located.
Or, if optical:
C. If it is an optical mouse, try putting a clean piece of white paper under the mouse. See if that solves the problem. An Optical mouse seems to work better when used on a white (or at least light colored) surface.
If none of the above apply, try the following diagnotic steps:
1. Do a search for the file: pointer32.exe
Let me know if you find the file. You will need to allow hidden and system files to be included in the search using the 'Advanced" search. (this file may be infected with a trojan worm virus called: W32.Randex.R
Symantec Virus Information page If you find the file, I suggest you update your current Anti-virus program and run the scan to see if it can locate and remove any infected files. If none are found, then the pointer file must be clean of infection. And I note that you have already checked for a virus. I mention this only to confirm that the antivirus software has a fresh update before the scan. If so, then try using the virus scan at

2. In the meantime, do you have an older mouse that you can plug into your computer? If so, you can shut down you computer and then unplug your current mouse and substitute the older one. If not, go to step-3. Restart your computer and see if the problem is still happening. If the problem does not return, I would guess the problem is with the mouse.
3. Go to the Control Panel, Mouse and look at the list of pointers. Choose something different from what you're currently using. See if that pointer does not flicker. If if does not, then I believe the problem may be that mouse pointer driver file. If the problem persists, then I would want to know if you found the file noted in step-1.
4. Reinstall the mouse driver. First, close all running programs, then:
5. Go to the Device Manager and select your mouse. Uninstall it and then restart your computer. During restart, your mouse driver will automatically be reinstalled.
a. Right click My Computer
b. Choose Properties
c. Click Hardware
d. Click Device Manager
e. Click + sign next to Mouse
f. Right-click on mouse entry and choose "uninstall" (
See this picture)
g. Restart your computer.
Note: you may not need the following steps, but just in case:
If unistalling the mouse causes it to stop working immediately, the following explains how to use the keyboard keys to:
Close the Device Manager Window
Restart the computer
To close the window, use the Ctrl + Alt + Delete keys and the Tab and Arrow keys to select the "Applications" tab. Use the keyboard arrow keys to select any running applications and the Tab key to highlight the "End Task" button. Press Enter to "End Task" on the listed applications.
Close the Windows Task Manager window using the Right-Click menu key (usually located on the keyboard between the right side Ctrl key and the Window Start menu key. You keyboard may have a right side Alt key instead of a Windows Start menu key).
Then press the left side Ctrl key to open your start menu, and your arrow keys to select "Turn Off computer" and the "Restart". Press enter to restart the system.
I hope this helps!
