Why Do I see the “Shield for Safari” Pop-Up?
Tech support scams and browser-based scams such as Shield for Safari originate from various suspicious domains. Do you recall visiting a website that falls into the suspicious category?
Keep in mind that usually there are many suspicious domains rotating these scams. It is also possible that the pop-up message is triggered by a potentially unwanted program (PUA), that sneaked into your system without your knowledge.
If you visited a suspicious website, you could also be witnessing fake alert messages about viruses and other issues detected on your Mac. In this case, the “Shield for Safari” pop-up will not be the only one flooding your browser.
As to why scammers are spreading such fake pop-ups, messages of this kind are often promoting rogue security software.
If you have such a rogue product silently installed on your Mac, you may have become a “victim” of the so-called bundling method. This method means that legitimate software is installed together with third-party utilities, usually classified as PUAs. The bundling of software is done for monetization purposes, and is mostly popular among developers of adware (ad-supported software).
In this relation, the PUA that may be causing the “Shield for Safari” pop-up is most likely ad-supported as well. Adware, which can be anything from a browser add-on or extension to a PUA, compromises commonly used web browsers by tweaking their settings to display plenty of advertisements and collect user data.
