Looking for the best Mac Ad Blocking solution {JUSTICE HAS PREVAILED}

I am having more and more of my customers come in believing they have viruses. They are almost stopped from web browsing because of pop-up ads. Most have MacKeeper installed. What I am looking for is the best ad blocking software. What have you tried and how effective is it?

UPDATE 5/19/15

This problem is becoming much greater with my customers. The anti-virus programs are not blocking sites like "" which locks up Safari. Anyone have better suggestions on preventing this kind of attack?

MacKeeper refund ads will run on Facebook as part of class-action lawsuit settlement

Think about the concept of trusted hosts and how it can be expanded to prevent unwanted activity. In essence creating your own white list of what is allowed to attach to the computer.


I went back to Norton and put it on 10 machines and it seems to be effective. But woah be to anyone who contacts their Indian tech support. I will not ever put another customer into Norton while this antagonist, brick wall tech support exists. I have moved to Webroot and had no problems.


I like Kaspersky.

Looks like most anti-virus software will not handle the Adware, Malware or plishing sites, ( that lock up browsers. To rectify this issue if it has you locked up, first force quit the app, (option-command escape). Next restart it and hold down the shift key. Do not go back to the infected site.

Avoid installing any thing that purports to "Fix your Mac". Clean my Mac, MacKeeper, MacDefender, MacProtector, MacSecurity, Genio are ones to stay away from. Do not follow any links to "Repair your Mac". Always check a phone number before calling by doing a search for Scam & that number or link. BE Paranoid! MicroSoft is not calling you!

The way this scam works is that a hacker takes over a legitimate website, and this directs you to a a fake website that pretends to scan your Mac and find malicious software. It then convinces you to download the program to check for the malware, and enter your Apple ID and password to install the program: this program itself is the malware.

Over time it will pretend to scan your Mac, pretend to find problems, and try to get you to enter your credit-card details to fix the problems. If you enter your credit card details they are passed on to scammers who try to get money from your account.

What to do when a website says you have malicious software on Mac? If you are browsing a website and it claims to have detected malicious software, malware, or a virus (or simply states it has "detected problems" with your Mac), then follow these steps:

If you're in Safari (or another web browser) and get a warning about malicious software, virus, or problems detected, quit Safari by choosing Safari > Quit. If Safari refuses to quit, force-quit the app (Control-click the Safari icon and choose Force Quit).

Go to the Downloads folder and drag any install files, or files that you don't recognise, to the Trash.

Empty the Trash (Control-Click the Trash icon and choose Empty Trash). By doing this you will dodge the problem in the first place. You haven't installed any software, or handed over your credit-card details. I'd suggest you don't return to that website.

How to remove Mac malware (for free): How to protect your Mac from malware in the future

Now that you've checked and removed any malware from your Mac, you may want to ensure that your Mac doesn't get any malicious software in the future.

Here are some tips to follow to ensure you don't get any more malware:

Ensure your Mac is up to date. Open the App Store app and click Update All.

Turn on automatic updates. Open System Preferences and click App Store and select the option Automatically Check for Updates. Make sure both Install OS X Updates and Install System Data Files and Security Updates are also both selected.

Make sure the Mac only allows apps from trusted developers. Click on System Preferences > Security and Privacy and General. Check that the option under Allow Apps Download From is set to either Mac App Store or Mac App Store and Identified Developers. If it is set to Anywhere, then click on the Lock icon, enter your password, and change it to either Mac App Store or Mac App Store and Identified Developers.

Get your software from the Mac App Store or from developers you know and trust.

Here's the best of anti-virus software:

Obligatory notice: Blocking ads prevents web publishers from supporting themselves, ad revenue is what pays the bills for websites.

MacKeeper is JUNK malware… informed users should know this but…. what are you going to do with someone so naive they believe a popup add that informs them they must clean their computer?.

IMnsHO Ad blockers as a rule are scams… they all run whitelists (in other words some Ads are OK - those that pay a fee to the developer).

Depends also what browser they are using.. Safari, Firefox or Chrome AdBlock seems to be one of the favorites. . . but it's also one with a whitelist.

If this answer is acceptable please remember to return and mark it accepted.

Adblock, also seemed to me, the best on a short list of poor alternatives. Thanks for your input.


MacKeeper is definitely junk.

I just had a laptop in that would slow down almost to a halt. Then MacKeeper pops up to inform you that the laptop needs cleaning/repairing and that viruses are detected.

Once you run MacKeeper, the laptops runs ok for a little while then back again to the same scenario. I dragged it to the recycle bin, keyed in the password to have it removed and INMEDIATELY got a "enter your password" prompt to run "MacKeeper Uninstaller" although there was no such *.app in the applications when I first checked. I guess it was trying to trick me into approving something else.

The prompt wouldn't go away so I killed Safari and Finder and proceeded to delete all the MacKeeper (and another app's) entries in all the registries. I didn't even run a virus scan afterwards, and the laptop's been running fine for a week. It seems MacKeeper was slowing the system then unlocking it when you ran it.


Check your library for residual mackeeper items, also run spotlight to help find anything else.


I did that. I looked in /Library and ~/Library and /System/Library

Google Chrome, AdBlock and AdBlock Plus. I use BOTH these plugins to prevent these b******ds from infecting my PC and Macs. I don't care that the ad's may be supporting these sites, but they need to regulate them! they are too malicious nowadays! I'm too scared to use my iPhone to browse the web because of these popup/ ultra invasive ads. I hate ads because of this and I use two ad blockers to prevent malware.

I would also suggest reporting bad websites to apple's bug reporter that take a malicious advantage of security flaws in Safari. totally worth it; reporting the sites allows them to fix these holes, you see ;)

Please give a link on this.


Mayer you'll need to be a registered Apple developer with an active Developer Apple ID, Here's the page to sign-in: Using Apple Bug Reporter. The other way is to use this feed back form: Mac OS X Feedback.
