AVAST will not open
« on: December 09, 2017, 05:30:31 PM »
I apologize for this probably being a problem already answered but i could not locate the solution. With XP I could operate Avast through the back door, sort od speak, but I could not access up front. I uninstalled Avast with AvastClear and reinstalled. When clicking on the icon all I get is a blank grey box, what do I need to do now?
Thanks,
Bill

Does your XP installation include SP3 ?

Does your CPU chip support the SSE2 instruction set ?

Are you connected to the internet when installing avast ?
