Popup scammer

UPDATE: Unbeknownst to me, (because he didnt tell me), My friend actually let this asshat into his pc. When he stopped the whole process, the scammer restarted it in safe mode. It took me a while to figure this out, but apparently, he did a few other things too. I am trying to repair the damages from 1000 miles away. I would Appreciate it if someone could call these scumbags and syskey them or something

talked to an elderly friend of mine but he didnt let them connect. he thinks this is the same clown whos been calling him for 2 years this was a popup however
