AV Security Suite Virus

Has anyone else been getting a virus called AV Security Suite while browsing Chess.com? I left my computer open at this site yesterday and went to dinner; I came back and I kept getting popups and fake security alerts from this program, which is widely acknowledged as malware. I managed to run Malwarebytes and take it off, but I just started getting the popups again, this time on my work computer, again while browsing Chess.com. I'm not the admin on this computer, so I can't even install Malwarebytes to fix it! Is anyone else having this problem?

(The only other sites I've had open are Foreign Policy, CNN, and the BBC, all of which are major, heavily trafficked, very reliably sites which I doubt would have viruses!)

Never had any problems with virus on this site & have been playing on here for over a year and a half
