Thanks. Yes, the virus program says it isolates it but it shows up every time I go there. And it's only that site. some say it's a virus and offer suggestions for removing it but I suspect those are just more trouble. Reddit had the best, said it's a mining tool and it makes the computers overwork such as making the fan run. My fan started running a week ago and while I think I have that partly under control I wonder if this was doing it. Reddit said it's a way of mining for bitcoins in computers that run adblock, that it's not really dangerous but annoying as hell. Yeah, I can think of one or two people who might want to play havoc with that site. UBlock then to block it? Can I use that with my virus program? thanks much.
