Mac security provided by MacKeeper.

Privacy leaks. Data scandals. Social media backlash. Bad things happen when users don’t take internet security seriously. Installing security software for Mac is as necessary as locking the front door of your house. The truth is, a locked Mac is a safe Mac. MacKeeper makes it easy to block viruses and find your Mac if it goes missing. Get MacKeeper and sleep tight — your Mac is protected.


Four signs you need internet security for Mac.

Scary virus alerts everywhere online

Next time you see “remove 5 viruses now” on the web, just close the tab. It’s fake. Browser functionality can’t detect anything malicious. Remember, only specific security apps like MacKeeper can spot viruses.

You often connect USB drives to Mac

Sometimes transferring your documents or photos may end with a nasty surprise. Running a Mac security scan is a good idea. MacKeeper can scan a specific device or folders and stop the virus before it spreads.

Annoying ads drive you crazy

Keep seeing intrusive ads? Chances are you Mac is infected with adware generating tons of popups. The best way to check it is to scan your Mac with adware cleaner.

You can’t find your Mac

Who knows why your Mac went lost. Well, MacKeeper knows. Use the Track My Mac phone app to see your Mac’s location and lock it remotely. What’s more, you’ll see a snapshot of whoever entered the wrong Mac password.

Start your Mac security scan. It’s easy.

  • I've been using MacKeeper for a few years now and it has done an exemplary job of keeping my Mac running smoothly, finding issues (downloaded by my offspring) and fixing them. I wouldn't hesitate to recommend it to any Mac owner. This new version with a real human on the other side of the screen is great! I'm thrilled.
  • Andrew was very helpful during this process. I hope he will continue to assist me on my future needs.
  • MacKeeper is worth my small financial investment with big returns in my computers' security, memory and efficiency. I recommend this service to everyone.
  • Habe mit Hilfe von Andrew die App getestet und zu einem günstigen Preis den Virenschutz installiert. Super Hilfestellung! Vielen Dank Andrew!👍
  • Andrew performed exceptionally. Had a great experience and hopeful to get my mac running quicker and more fluid.
  • Our computer system was scrammed and MacKeeper cleared our system thoroughly - which took over 3 hrs. Problems solved.
  • Have had issues before and had an immediate response and issues were fixed. Will continue stay with the best.
  • The problem I was having was solved in a very short time. I am completely happy with my purchase.
  • It was informative and educational and would recommend to other MAC users.
  • I enjoyed the ex[pertise of the knowledgeable person on the phone line. I appreciated the knowledge and the rapid way he could handle things. I did feel as though he was pushing too hard about buying the service. I had to say several times that I did not want it. The service was very good....I just didn't like the hard sell approach
  • Good info and the tech was very pleasant. But I still hate remote logins. I could have done 80 % of this myself. Still I rate it worthwhile.
