The end of flash is near, and I think the ransomware attacks will speed it up. Responded to another one last week, that is, another PC intervention. Got into Task Manager and quit the browser. Had one on a Mac once, a stronger version. I could Force Quit it, but it kept coming up time after time. Finally I had to go and delete the script files that made it run. The ransomware malware is a very serious problem, and after the hospital attack, they are pushing to make the crime a felony extortion crime. Some of these can be picked up by going through routine links, I picked mine up by following a link on Yahoo.
