I will try what you say, i really appreciate your help.
I also may not have done the system restore correctly, in that I didn't go back to a previous save point. i just turned it off then on again
Tbh, I am confused about this aspect. i guess the system makes a series of points in time that can be gone back to.
But, let's say there are 50 of these, and the trojan got in at checkpoint 35, then do i need to do this
Refresh to 50
Refresh to 49
