I've been dealing with this Chrome malware for awhile now, and I can't identify where it's coming from. Very occasionally, when I click on a top link in Google, it'll redirect me to a site that looks like this (always the same green circle with the text "Loading"), and then to adware. The redirect is located at a new domain every time, but it's always the same green circle. Can anyone help? I only have uBlock Origin installed and I installed it via the Chrome Store. I'm on OS X Mojave. Malwarebytes turns up nothing (PUPs enabled).
