Use free Malwarebytes Anti-Malware for Mac/ AdwareMedic to remove adware

http://www.adwaremedic.com/index.php

Download, install , open, and run it by clicking “Scan for Adware” button to remove adware.

Once done, quit Malwarebytes Anti-Malware.

or

Remove the adware manually by following the “HowTo” from Apple.

You may have installed ad-injection malware ("adware").

Don't use any kind of "anti-virus" or "anti-malware" product on a Mac. There is never a need for it, and relying on it for protection makes you more vulnerable to attack, not less.

This easy procedure will detect any kind of adware that I know of. Deactivating it is a separate, and even easier, procedure that doesn't involve downloading anything.

Some legitimate software is ad-supported and may display ads in its own windows or in a web browser while it's running. That's not malware and it may not show up.

If none of your web browsers is working well enough to carry out these instructions, restart the computer in safe mode. That will disable the malware temporarily.

Step 1

Please triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:

~/Library/LaunchAgents

In the Finder, select

Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. Press return. Either a folder named "LaunchAgents" will open, or you'll get a notice that the folder can't be found. If the folder isn't found, go to the next step.

If the folder does open, press the key combination command-2 to select list view, if it's not already selected. Please don't skip this step.

There should be a column in the Finder window headed Date Modified. Click that heading twice to sort the contents by date with the newest at the top. If necessary, enlarge the window so that all of the contents are showing.

Follow the instructions in this support article under the heading "Take a screenshot of a window." An image file with a name beginning in "Screen Shot" should be saved to the Desktop. Open the screenshot and make sure it's readable. If not, capture a smaller part of the screen showing only what needs to be shown.

Start a reply to this message. Drag the image file into the editing window to upload it. You can also include text in the reply.

Leave the folder open for now.

Step 2

Do as in Step 1 with this line:

/Library/LaunchAgents

The folder that may open will have the same name, but is not the same, as the one in Step 1. As in that step, the folder may not exist.

Step 3

Repeat with this line:

/Library/LaunchDaemons

This time the folder will be named "LaunchDaemons."

Step 4

Open the Safari preferences window and select the Extensions tab. If any extensions are listed, post a screenshot. If there are no extensions, or if you can't launch Safari, skip this step.

Step 5

If you use the Firefox or Chrome browser, open its extension list and do as in Step 4.

That's why I tell people not to use "anti-malware" software. It will never work reliably.

My suggestion involves nothing more difficult or dangerous than what you do with the computer every day. It's less dangerous than downloading unknown software just because a stranger on a message board tells you to, and by far less dangerous than installing malware, which you've already done.

That's Step 1. Anything from the other steps?

Back up all data before making any changes.

In the folder arranged as shown in the screenshot, please delete these items:

#4 and #5 ("Genieo")

Log out or restart the computer.

Uninstall any Safari extensions you don't know you need. If in doubt, remove all of them. None is needed for normal operation.

Do the equivalent in the Chrome and Firefox browsers, if you use either of those.

Reset the Safari home page, if it was changed. You may need to do the same in the other browsers.

From the Applications folder (not shown in the screenshot), delete items with any of the following names:

InstallMac

Genieo

Reset Search

Uninstall Genieo

These steps will permanently inactivate the malware, as long as you never reinstall it. A few small files may remain in hidden folders, but they have no effect.
