Hi John, Thank you for your help.
Unfortunately, I can't click on system preferences or anything else because it is completely disabled. There is a tab open on my screen that says
"Welcome 2 #Basedasia", which I assume is the hacker's site, and there is an "OK" box flashing, which he wants me to click on, and which I'm refusing to do. Everything else is completely disabled.
No, it's disabled.
Thank you so much, John, it worked!! You've been very helpful, and I'm very grateful!
Have a good night,
