is adware medic good to use on macbook pro

Yes. It's one of the few recommended anti-malware apps there are for the Mac. It's a "run once and done" program and doesn't lurk in the background.

There is no need to download anything to remove the common types of ad-injection malware. Follow the instructions on this Apple Support page.

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.

Linc, the steps you've outlined are indeed straightforward and were much appreciated. But with respect and for what it's worth, after trying your method I still could not fix my problem with the MacKeepr malware - and I concede it may have been user error on my part, but for whatever the reason, it didn't work.

So instead I DL'd Adware Medic and it worked like a charm, and it was also dead-easy to use.

If one has zero skills/patience/time to conduct even the most rudimentary DIY computer maintenance (myself, for instance), then AdwareMedic is well worth it. I have no connection to AdwareMedic btw, just a very happy and grateful user, who donated a couple of bucks after a satisfactory experience (the software is free otherwise). Of course, as in all things, YMMV, but I wouldn't be so quick to discount it.

...and all that to say - YES, it's good to use. I just used it on my mid-2010 MBP 15" running OSX 10.9.5 and it worked like a charm. Very happy with it so far.
