Was perusing FB Vids when red screen pops up and tells me computer locked.
I did a hard shut down and computer was ok when restarted. Then about a week later it has started writing zeros to all boxes I click on. Before clicking these boxes look normal.
Either it has blocked access to Norton and MalwareBytes or the last Windows update uninstalled them. (It did this to my Win10 machine).
Any suggestions on how to attack this problem will be greatly appreciated.
