Suspicious safari popup window
This popup shows to me every 1 hours or so. If I click on it, the Eset Cyber security, prevent me from accessing the site, as it might be dangerous for the Mac.
Yet, neither Eset, AVG cleaner or Malwerbytes were not able to find any virus, spam, malware or what so ever in the computer.
What should I do, to clear the computer from "this"?
Thank you for any suggestions.
MacBook Pro with Retina display, macOS Mojave (10.14)
