How do I uninstall Install Mac adware?

Unfortunately whatever you saw from Linc was a narrowly-focused suggestion and unlikely to help completely remove adware. Download and run AdwareMedic from http://adwaremedic.com/index.php.

Click here and follow the instructions, or if there’s a type of adware not covered by them on the computer, these ones. If you'd rather not remove it manually, you can instead run Adware Medic; this link is a direct download.

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

You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.

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 (OS X 10.10 or later)

or

Download updates automatically (OS X 10.9 or earlier)

if it's not already checked.

I would suggest that you DO download AdwareMedic. It is a very quick download and when opened will run very quickly. Suggesting that a download is more complicated or will take longer than following the multistep procedure advocated by Linc Davis should be viewed as an erroneous inference.

In addition, the complicated procedures advocated by Linc Davis, by comparison, invites the possibility of unnecessary errors and mistakes. May I also mention that AdwareMedic is used by many Apple technicians in many genius bars in lieu of the Apple support article procedures. It has also been recommended by Apple telephone support and is a 'Recommended' procedure as designated by Apple employees on these forums.

So keep it fast and simple, use AdwareMedic. If there is no success, then by all means try the cumbersome procedure posted by Linc Davis. But the chances are that you will not need to. I have used AdwareMedic and I endorse it.
