Uninstall Yahoo Powered Search

If that problem is indeed adware installed on your Mac, you don't have to install anything more to get rid of it. You will need to provide some additional information though, so that you can identify what to get rid of and how to get rid of it. Start below.

Navigate to the following folder, and post its contents in a screenshot.

~/Library/LaunchAgents

To open that folder, copy the entire line above and paste it in the Finder's Go menu > Go to Folder... field. It should look like this:

Take a screenshot showing all that folder's contents, and post it in a reply. To take a screenshot read the Appendix in the following User Tip: Writing an effective Apple Support Communities question.

There will be additional instructions to follow.

For a description of how this may have occurred, how to avoid it in the future, and for Apple's recommended actions read How to install adware. You may also wish to read Beware bogus Adobe Flash "installers" which lead down the same path. The only way to prevent installing adware is its recognition and avoidance.

Review your Gatekeeper settings: OS X : About Gatekeeper - Apple Support. Gatekeeper is designed to help prevent you from inadvertently installing garbage software.

Try going to Safari/Preferences/Extensions and disable all extensions. Quit Safari, reopen, and see if the website will now load. If so, enable extensions one or two at a time until you find which extension is causing the problem.

Removing adware manually involves identifying the root cause. Look first at the property list files you find in

~/Library/LaunchAgents

/Library/LaunchAgents

/Library/LaunchDaemons

Look for the program arguments inside that tell you what their executing.

The problem with handling this manually is that you may mistakenly delete things you think are malware but aren't.

If you know what you are doing, then it is fine; but there is a risk that something will break sometime in the near or not-so-near future... at the very least you should make a note of what you deleted.

You're right! I see it there. I feel like a dope. I notice there is an "uninstall" application inside that folder. Wondering if I should "uninstall" or just trash it like you did. I'd be interested to know if you have stopped getting the occasional UPDATE prompts. Thanks!

This pop up window just showed up for me for the very first time and I havent clicked on it. I closed all my web browsers thinking that it would close too but it didnt. It stayed there. So I checked online and none of the answers I found have worked so far. It is not a addon or an extension in my browsers and it is not in my Applications file. Any ideas anyone?

You allow your 10 year old on your Mac on an account that is capable of installing software?

Personally I would only allow a 10 year old on my Mac as guest. Or if guest was too restrictive then an account that was limited so that it was not capable of installing anything on the Mac.

I got the same popup, but didn't find the folder in my Applications folder. Ran a Spotlight search, found the uninstaller, and removed it. Also found Chromium and removed that as well. I think it downloaded along with uTorrent (also removed).

I found Yahoo Powered Search in my applications folder. Moved it to Trash.

It sounds like you have adware install on your MBA. Try Malwarebytes | Malwarebytes Anti-Malware for Mac

This was perfect and helped greatly. Found stuff that Malwarebytes didn't.

If you don't mind me asking, what was found that Malwarebytes didn't detect?

Same here. I have an iMac 3.2Ghz 27" (2015). It's extremely annoying. Yahoo should be sued over this. IMO.
