How to get rid of Yahoo search on Mac

When it comes to web search biases, beauty is in the eye of the beholder. Most people prefer using Google, some like Bing, and some are more accustomed to looking up information on Yahoo. Everyone is free to specify these preferences in their browser’s settings. But what if something prevents this decision from taking effect? That’s precisely what happens when Mac malware spares its ugly fangs. One of the most common species of this nasty code overrides a user’s Internet defaults by limiting all searches to Yahoo, even if the favorite provider is completely different.

Yahoo search redirect is one of the top Mac malware schemes

To set this exploitation in motion, cybercriminals contrived a multi-pronged malware distribution scheme that may ensnare even the most vigilant Mac owners. A classic technique for spreading these shadowy applications involves tech support scams in which a specially tailored web page reports imaginary threats on the computer and urges the user to install pseudo-protection, which is a browser redirect virus in disguise. Another vector relies on pop-ups displayed on malicious or hacked sites that say critical software updates are missing and instruct the visitor to install the latest version. One more tactic is to inject a dubious app into seemingly harmless freeware installers that quietly promote bundles instead of a single program.

These different tricks have a common denominator – they all result in the installation of malware that reorganizes browser settings without permission. Counterintuitively, it doesn’t hard-code URL in the default configuration of Safari, Google Chrome, or Mozilla Firefox. Instead, it embeds an auxiliary value that ultimately forwards all hits to Yahoo search. These “helper” sites include,,,,,, and

The campaign is backed by a network of affiliated junk services such as Safe Finder

A particularly off-putting thing about this unwelcome tweak is that it can’t be undone by re-entering the correct settings manually. That’s because Mac malware, in general, and adware, in particular, have developed significant persistence mechanisms in the course of their evolution. The abuse of macOS configuration profiles is the pillar of this tampering. Normally, this feature allows network admins to enforce corporate policies by implementing a set of restrictions on company-issued computers. Crooks have learned to turn this usefulness upside down.

At an early infection stage, the malicious program that underlies Yahoo search redirects accesses the command line utility and uses it to create an evil device profile. This entity outlines system behavior that fits the attacker’s objectives, including the search engine, homepage, and new tab preferences in web browsers spotted on the target Mac. Therefore, any changes on the victim’s end are completely disallowed or reversed after the next system login.

How do malware makers benefit from this condition? It’s mostly about affiliate revenue. As mentioned above, the plagued web browser queries transitory domains before resolving Their role is to intertwine the scheme with ad network APIs, which brings revenue to malware operators. This is a well-trodden path that proved to be highly lucrative. If you have found yourself in this adverse situation, the only way to disrupt the bad guys’ plan is to get rid of the malicious application and its traces left across the system. The following tips will help you out.
