Yahoo search engine virus

Download and run Malwarebytes. Malwarebytes was developed by one of our own colleagues here in ASC and is about the most proven anti-malware software for Mac. All you need is the free version.

After that restart your ac and then go to Safari > Preferences > Search and choose the search engine you want.

I just unselected a nasty little program called DefaultProducts 1.0 listed in Safari Extensions and voila, Google is back. DefaultProducts says " it can read all webpage contents, including passwords, phone numbers and credit cards" !! I have no idea how it's all related but there you go.

I spent hours trying to remove the Yahoo search engine virus and failed. I came on Apple Support, saw macjack's suggestions run Malwarebytes and no exaggeration, five minutes later my Mac was clean. Higly recommend this as your solution.

The Malwarebytes was a huge help and I will be running that regularly now. Also, I cleared my caches/cookies and history for good measure. After a reboot, my search engine was back to Google as preferred. But ugh! That whole Yahoo hijacking my searches was incredibly annoying!

I had the same problem and was frustrated just like everyone else.

I went to my System Preference and look for, an icon that looks like a bottle cap and a check mark in it., Called Profiles.

Delete the items in there and that worm goes away.

I have had it come back up but i do the same thing and it goes away again.

I have also switched to Google chrome and left Safari.

Hope this helps everyone.

I am not a poster but this was such a relief to figure out. I wanted to share this in this forum.

I'd never suggest using any of those antivirus or so-called "cleaners", but Malwarebytes is safe and recommended by Apple Support Reps to remove malware from your Mac.

Here are manual removal directions, do not download any other so-called "cleaners" they can do more harm than good.

Which three browsers?

I'd flush the cache & remove the cookies

& reboot/power down

then - flush PRAM if necessary

then remove all the extensions,

checking to see if there's anything loaded in boot up process that might need to be turned off

Malwarebytes didn't work for me, what did was Antivrus Zap - Virus & Adware £8.99 from App Store.

Hey i know this is late but i found out

go to the system preference then click profile if you see ultrasearchapp then remove it by clicking the - sign below your left side. if it is 2 of them delete them both

Click on the Apple icon, then go to profiles lower right hand area...

Malware scan doesn't take care of it. I've followed all kinds of protocols through Apple but none of them work. My search preference has always been google, but when using search it's always yahoo. Very frustrating!

I have malware called Anysearchmanager.com which has taken control of my searches to always do them on yahoo and I can't do anything with it. I don't want to trust anything downloaded to fix it because I suspect thats a scam like mac keeper. Why aren't Mac all over this ****?
