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.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 search.yahoo.com.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.Special OfferThe Yahoo redirect virus may re-infect your Mac multiple times unless you delete all of its fragments, including hidden ones.

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 search.yahoo.com 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.

You may have heard it's said that Macs don’t get viruses. That there’s no Apple virus. You may even have said it yourself. Sadly, it’s not true. According to the Apple Insider portal, the number of detected Mac viruses jumped up 60% in 2019. And, it’s not just viruses you have to be wary of. There are all sorts of different forms of malware, from bits of code that download themselves and show you adverts for things you have no interest in, to really nasty bugs that steal your personal data.
How do I know if my Mac has a virus?
Before you remove a virus from a Mac, you need to be sure it actually has one. We’ve covered that in more detail in this article but here are a few pointers.
These symptoms may mean your Mac has a virus, although there could be other explanations.
How to remove a virus from a Mac
Thankfully, there are lots of ways to do it. And Mac virus removal doesn’t have to cost money.
1. Delete browser extensions
One of the most common types s of malware comes in the form of browser extensions. Even extensions that aren’t particularly malicious can be annoying, and if you didn’t deliberately install them, they’re malware. Here’s how to get rid of unwanted browser extensions.
Safari
Chrome
Firefox
2. Uninstall apps
Malware comes in lots of different forms. And it even comes disguised as security software to help you get rid of viruses! Devious, huh?
If you’ve inadvertently downloaded an app that turns out to be a virus, you need to uninstall it immediately. There are a couple of ways to do this. Here’s the hard way.
The easy way: Uninstall apps in a few clicks
If you don’t know the name of the application, it’s more difficult. But if you use CleanMyMac, all you have to do is scroll through the list of applications and look for any you don’t recognize or don’t need and remove them. CleanMyMac removes every trace of an app, including files that you may overlook when you remove applications manually. This is particularly important for viruses, so it’s much better to use CleanMyMac.
What's makes this method even better, is that CleanMyMac X also shows you app leftovers that remained after the main app is gone. 3. Use a malware removal tool
While the above steps work very well in lots of cases, sometimes the Mac virus removal means using a dedicated application to scan and remove malware from your Mac.
There are lots of these applications available, and many of them are either free or allow you to at the very least scan your Mac for free to find out whether you need to take action. Be careful, however. It’s important to choose a tool from a reputable vendor. If you just google ‘Mac antivirus tool’ some of the results may well be for tools that are themselves malicious and instead of removing viruses from your Mac will infect it. We recommend using CleanMyMac X.
It can identify thousands of malware threats, including adware, spyware, ransomware, worms, cryptocurrency miners. And if CleanMyMac finds something suspicious, it will offer immediate removal. Here’s how to perform a full system scan:
4. Escape the virus: Create a new user profile
Usually, viruses are attached to a particular user profile on your computer. In this way, they are able to seize control of your admin profile. But you can start if from scratch and create a new user on your Mac. Don't worry, you will be able to transfer all your important data from one user to another.
Go to Apple menu > System Preferences, click Users & Groups.
To move your important information from one user to another, you will need to access the Shared folder.
Can you see the Shared folder? Here you can copy the needed files from your old user account. Hurray, you've started a clean, virus-free life!
Bonus tip: Clean up your login items
Login items are apps that launch automatically upon startup. Malware programs would often sneak into your login items without you knowing. How to prevent them from launching?
From here you can manage them using the [+] and [—] buttons.
How to disable the invisible agents
Some small supporting applications never show up in the Login items. They are called the Launch agents and may as well be hacked by viruses. You can find them with the universal Mac cleaner, CleanMyMac. This app is notarized by Apple, so you are safe using it.
How many apps do you see there? Remove any flash players, automatic updaters, or everything else that you find suspicious. Even if you deleted the main app itself, its launch agents may still occupy your drive. Here is what I have:
To prevent your Mac from infection, the above app has a real-time monitor tool. It checks whether no harmful apps place their code in your Launch Agents. It monitors several such locations that could be gateways for viruses.
How to get rid of a virus on a Macbook Pro (or any other Mac) if all else fails
If you’ve run through all the steps above and are still having problems trying to remove a virus from a Mac, the next step is to restore from a Time Machine backup. The benefit of restoring from Time Machine is that you can do it quickly and easily by booting into the recovery partition and you can choose to backup to a state just before your Mac started behaving erratically.
The downside of this option is that any work you’ve done since the backup you restore from will be lost. You could manually copy files from your Mac to another drive or cloud storage service before you restore and then copy them back afterward. However, if one of those files is infected, you risk contaminating your Mac all over again. If there are documents you really need and that aren’t backed up elsewhere, use one of the antivirus tools above to run a scan on them before you copy them to another disk. That way you’ll know they’re safe.
Here’s how to restore from a Time Machine backup
Your Mac will now return to the state it was in when you made that backup.
If you don’t have a Time Machine backup to restore from, the last resort is to reinstall macOS. This is a ground-zero approach. You’ll need to wipe your startup drive completely clean and start again. That means reinstalling all your applications and copying all your data back to your Mac afterward. If you have a recent backup of your data, from before your Mac became infected, you can use that to copy data from after you re-install. If not, you’ll need to back up important files now — but scan them with an antivirus tool first to make sure they’re not infected.
To perform a clean install of macOS, you’ll need a bootable installer disk. Creating one is beyond the scope of this article, but there is a comprehensive guide here.
Once you’ve made your bootable installer, plug it into your Mac, go to System Preferences, choose Startup Disk and select the disk you just plugged in. Restart your Mac, holding down Command-R and do the following:
As you can see, there are many different ways to remove a virus from a Mac, depending on how badly infected it is and what kind of virus it is. The main thing to remember is if you suspect your Mac is infected, don’t worry. It can be fixed!
