How to get rid of a yahoo virus that keeps redi...

I have google set as my default search engine and no matter what i do, as soon as i enter a subject in the address bar, it gets redirect to yahoo search engine which i don't like. I have tried doing all kinds of research to remove it and nothing seems to work. Also, I am not sure if these two viruses are related but Mackeeper also starting popping up all the time around the same time this started to happen. It opens up about 5 tabs on its own sometimes and i don't know how to fix that either. I am pretty sure that this is some sort of virus. If someone knows of the same problem and has gotten rid of it, please help!

Thanks

These aren't viruses. It's adware. This is how is gets installed: How to install adware

There is no need to download anything to solve this problem.

You may have installed one of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it.

Back up all data before making any changes.

One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.

If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.

Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.

Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.

In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.

Still in System Preferences, open the App Store or Software Update pane and check the box marked

          Install system data files and security updates

if it's not already checked.

Thank you Esquared...i followed your advice and it really worked. This thing was driving me crazy for three days now.

Thank you Linc, there was a lot of useful information on that page!

WOW, these forums are great...beats going to the apple store !

This link contains instructions for manual removal.

Thanks for that, Esquared. I went into Firefox’s Tools down to Add-ons and removed the malevolent gremlin, so now I no longer see the pesky “Y” word when I want to look for something. My Google search engine has regained its supremacy in my MacBook, and from now onwards I’ll try to avoid the “Y” word like the plague.

Only the devil knows how my trouble started (it seemed to be after an out-of-his-depth technician fiddled with my computer for unrelated issues), but you’ve solved it for me.

It's really way simpler than all these answers...Go to preferences>click on the search tab>and switch the search engine to Google...that's all it takes.

Not that simple at all when adware keeps changing the user settings. From the very first line in the first post:

I have google set as my default search engine…

@ achaker

Simplest thing to try first is what Linc already suggested. Open Safari's preferences and click on the Extensions tab. Disable all of them. Turn them on one at a time and test. If the problem returns, that's the extension causing the problem. Disable it again and remove it.

IT worked for me after months of ping to Yahoo. I check all the other spots listed above and none of those things were there. As soon as I changed the search engine all is right for me

Can't complain when it works. Sure wouldn't hurt for the OP to try. Though it seems something is redirecting all Google searches to Yahoo.

There are no extensions on my wife's apple computer. Thank god I never bought an apple for myself. On a PC you can very easily disable unwanted search engines.

And why would you believe it's so difficult to do on a Mac? All you have to do is open Safari's preferences and choose the search engine you want your queries to open in:

hahahahahah....great!!! So many advises, information and suggestions I read on this page and at least, finally, Kurt Lang give the best, simplest and the only one advise, which helped! Thanks a lot Kurt, it was 1 second to change it! Now I have again in the URL space Google which is searching (and not anymore Yahoo)

You're welcome. Glad it helped.
