My wife's computer (mine is the same as hers, bought two, Running Windows 7), suddenly is having a problem with her desktop icons. They no longer work, must start programs by going to Start, etc. Right click and left click, both do not work. If I reboot, an icon will work (start the program) once. But, on exit, no icon on the desktop will work any longer. I have run current AVG anti-virus and Malwarebytes. Neither shows any male-ware problems.
Any suggestions as to why/how to fix dead icons?
