Removing Advanced Mac Cleaner on El Capitan
Is there an updated 2018 article on removing Advanced Mac Cleaner pop-ups from a Mac (I'm running El Capitan)? Past articles talk about removing it from Safari, but I get the pop-up on my desktop even when no apps are running, and I don't even use Safari as my browser. Thanks!
iMac, OS X El Capitan (10.11.6)
