How to Remove Yahoo Virus on Mac

Search engines have become part of our modern life. It’s the first thing you see when you open the browser. Sometimes, when you want to search online, the browser might take you to a totally different website. Yahoo virus is one example—although technically it is not a virus. When there are malicious malware or hijackers on your Mac, they will redirect your search to Yahoo Search. It is really annoying and will pose potential threat for your computer. This tutorial will give you a step-by-step guide to solve the Yahoo redirect problem.

Remove Malicious Browser Extensions

You also need to check if the default search engine on your browser has been changed by the malware.

For Safari:

  2. From the Menu bar, go to Safari > Preferences.
  3. Click Search. Check if the search engine is the one you usually use. Change it back if not.

Delete Suspicious Apps and Programs

There may be malicious apps that can hijack your Mac. Make sure to delete all the suspicious apps and programs.
1. Go to Finder > Applications.
2. If you see any malicious apps, drag them to the Trash.

Remove Malicious Profiles

Multiple profiles are very common on company or organizations’ computers. However, personal users might also find their Macs hijacked through a Configuration Profile. Follow these steps to check if your computer is threatened by it:
1. Click the Apple icon on the menu bar, then go to System Preferences.
2. Go to Profiles.
System Preferences - Profiles
3. If you see any unfamiliar profile, select it and click the icon on the bottom.
