This particular version of the malware takes safari fullscreen with popups that reappear when dismissed.
Moving mouse cursor to top of screen to reveal menu bar, then choosing Quit works... simpler methods like selecting "close tab" from file menu or 'command-Q' might also work.
Don't know if this malware automatically reloads if Safari (or other browser) is relaunched.
I used a malware scanner to locate and delete the files.
It's 'live' scanner should have thrown a dialog before this thing even loaded... too new perhaps.
Anyway, the clickbait's address (as it appears in the resulting tab) gets redirected at least once.
According to browser history this is, a now defunct, suspect address:
