Remove Yahoo Search redirect virus from Mac (Safari, Chrome, Firefox)

Learn how to get rid of the Yahoo redirect virus on Mac and stop recurrent unauthorized traffic forwarding in Safari and other browsers on a Mac computer.

Update: March 2020

When the prerogative of unimpeded web surfing slips out of one’s hands, things quickly get intolerable. In this scenario, doing a search via preferred service or simply launching a browser of choice will return a site the user doesn’t expect to see. If this is the case, the victims should look for malicious code that’s implementing this whole stratagem behind their back. When it comes to Mac computers, there are numerous marginal browser hijackers that never reach sizeable distribution volumes, but there are also major campaigns that last for years and span thousands of machines. The latter holds true for the Yahoo redirect virus, a plague whose prevalence demonstrates how important it is to stick with reasonable online hygiene. The main symptom of this incursion is an annoying web traffic rerouting activity, with the resulting page being

At this point, many readers will probably start wondering why the above-mentioned legit search engine is flagged malicious. As a matter of fact, it’s not – otherwise, the categorization is an utter misconception. Instead, the entire problem is about a perpetrating app that literally enslaves one’s web browser and forwards the bulk of the Internet surfing routine to Yahoo. Online traffic funneling from unique hosts is an extremely valuable asset nowadays, and the cybercrooks have contrived an intricate model to harness and monetize in their very own, nefarious way. The thing is, before a victim ends up on the reputable Internet giant in question as a result of the hijack, they get routed via a number of intermediary domains, and these hits actually count in the dodgy traffic monetization platform.

There are several dubious services operating under the wide umbrella of the generic Yahoo Search redirect campaign. Most of them are backed by potentially unwanted apps (PUAs) that claim to enhance Mac users’ web surfing experience but actually turn it upside down. Here are a few examples of these mainstream adware strains: Safe Finder (, Any Search Manager (, SearchMine (, and Search Pulse ( All of them force hits to their landing pages camouflaged as search providers. Predictably enough, though, none has a real proprietary information lookup feature, primitively redirecting every query to Yahoo. In most instances of this unauthorized redistribution of Internet traffic, there are intermediary URLs resolved en route to the destination. A common example is domain name prepended by lkysearchds[random digits] or similar random-looking string.

The aggressive phase of the raid is preceded by a furtive infiltration of the underlying malware into the Mac. This is typically an upshot of a bundling technique heavily used by both decent and unscrupulous software developers to cross-promote certain apps coming as part of a bigger installation package. Users don’t read the fine print these days, and that could be a source of serious quandaries. The Yahoo redirect virus may lurk in multi-pronged setup clients for what appears to be a legit software update or some useful free tool, such as a media downloader or video game. For instance, the fake Adobe Flash Player update popups are known to spread this electronic malady. The express installation option, which is most people’s favorite due to the ease of the setup, will silently pull in the culprit. The next thing you know, Safari, Chrome or Firefox on the Mac will start acting up badly.

Once the contamination has taken place on a macOS or Mac OS X system, the redirects to are usually triggered according to a specific pattern rather than haphazardly. The victims report their Google searches being forcibly diverted to Yahoo. Simply opening one’s preferred browser is another trigger for the predicament. All attempts to sort it out by defining correct URLs for the corresponding custom browsing settings are futile – the wrong values shortly reappear in there due to the persistent malware activity. Sometimes the defaults may even be right, with the interference taking place at a different layer of the host operating system. Under the circumstances, the cure should synchronously cover several areas of the affected system, as shown in the cleanup part below.

As outlined in the previous answer, browser troubleshooting alone is a no-go unless you remove the underlying virus first. You should stick to the cleanup walkthrough covered in the article to make the infection vanish.

Importantly, be sure to peek into your Login Items by going to System Preferences – Accounts. In many cases, the victims have a rogue entry named ‘Mac Mechanic’ in there – if found, delete it right away. This is a fake system utility that may have promoted the Yahoo redirect virus into your Mac in the first place.

In order to sort out the search engine replacement issue, go to your browser’s preferences screen and ascertain that the right search provider is selected as the default one. Additionally, disable suspicious browser extensions if spotted. A more thoroughgoing fix is to reset the affected web browser to its original state and redefine your custom settings afterwards.

If you are faced with a virus scenario, switching from Yahoo to Google as your preferred search engine is a much more complex procedure than tweaking these settings manually. You need to additionally get around the malicious app’s interference so that the benign changes take effect for good.

Here are the components and paths on your MacBook Air or MacBook Pro to scour for the potentially unwanted program: Activity Monitor, Applications, and Login Items. Anything that clearly doesn’t belong there should be deleted.

It’s not until the redirect virus has been removed from your Mac that you can get down to rectifying the browser settings. See the guide’s section called ‘Get rid of redirect virus in web browser on Mac’ for the appropriate instructions. Having completed these steps, go ahead and assign Google as your default search engine in the browser of choice.

Not necessarily. It depends on the methods leveraged to promote such a web service. Obviously, it takes enormous efforts and human resources, plus a lot of time to create and maintain a fully-fledged search engine. Only major companies can afford it. Meanwhile, the entities that wish to include a search feature in their online service can choose to outsource the functionality to Yahoo.

However, malware developers are known to abuse the Powered by Yahoo framework on a large scale. Their potentially unwanted apps forcibly change users’ Internet preferences so that the browser returns Yahoo search results combined with ads that normally don’t belong there. This explains why such an approach tends to call forth malicious inferences. The truth is that the inscription “Powered by Yahoo” becomes a sort of red herring in these traffic monetization campaigns.
