I’m on a MAC and the EXACT same thing happened to me when I tried to open Drudge. Took over everything and I could do NOTHING. EXCEPT use option/apple/escape. And it worked to rid my frozen computer of this crap. LUCKILY, I had hours before read that this kind of thing was happening, so I didn’t break down and hit “ok” when the pop up occurred. THANKS to FREEPERS who got the word out!
I used force quit safari. Then restarted then shut down and started her back up. Fine now.
