i have a windows xp system that had a pop up virus.
do not know which one. it did hijack the system - saying purchase anti-virus.
other than that, nothing would work in windows.
had my friend run malwarebytes. restarted computer.
now when you click on system restore for example, it says choose the program you
want to open this file with box.
anyone know what this is and how to fix other than a complete rewipe.
