If your Safari browser keeps redirecting your search results to Yahoo when you normally use Google or other search engines, you might have the Yahoo redirect virus, which is more similar to malware that was installed with something you've downloaded. To get rid of this Yahoo redirect virus, you'll need to do some uninstalling and deleting (there are some examples listed in the article, but since there are a variety of different malware problems, listing them all is impossible) before you can simply reset your browser's preferences. This wikiHow article walks you through the process of getting rid of the unwanted Yahoo malware on your Mac and aims to make it easy and simple enough for anyone to do!
Steps
-
Open Safari. Your first step in getting rid of the malware that redirects your searches to Yahoo is to make sure you get rid of any unknown extensions. -
Click Safari and select Preferences . The Safari menu is usually in the top left corner of your screen and the Preferences option is in the second grouping of menu items.- You can also press Cmd + , to open Preferences if you have Safari open.

Click the Extensions tab. It looks like a puzzle piece with a compass needle inside. -
Look for suspicious extensions. The extensions are listed on the left side of the window. You'll want to look for extensions that you don't remember installing, like Yahoo Redirect or Safe Finder.- Other extensions that might be malware are named Chill Tab, Search Baron, Search Marquis, Search Mine, Search Pulse, Search Tools Hub, etc.
- Click the extension to see more information, like the developer's name and the permissions it has.
-
Click Uninstall . This button is in the top right side of the window under the name of the extension.

Look for any suspicious process. Scroll up and down the list to make sure you recognize all the processes that are running.- If you find an unfamiliar process, click it to select it, then Google it to make sure it isn't an important system process. Because there are so many different malicious apps, their names are unique and they are too long to list here. Killing a system process could cause your Mac to freeze.
-
Click x . You'll see this x on a stop-sign icon in the top left corner of the window. This will close the process that's selected.- Click Force Quit when prompted.

Look for unfamiliar and suspicious file names.
