Helpful Links Regarding Malware Problems

If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide and The Safe Mac » Adware Removal Tool. Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.

An excellent link to read is Tom Reed's Mac Malware Guide.

Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.

If you require anti-virus protection Thomas Reed recommends using ClamXAV. (Thank you to Thomas Reed for this recommendation.)

From user Joe Bailey comes this equally useful advice:

The facts are:

1. There is no anti-malware software that can detect 100% of the malware out there.

2. There is no anti-malware that can detect anything targeting the Mac because there

     is no Mac malware in the wild, and therefore, no "signatures" to detect.

3. The very best way to prevent the most attacks is for you as the user to be aware that

     the most successful malware attacks rely on very sophisticated social engineering

     techniques preying on human avarice, ****, and fear.

4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on

    your computer is intended to entice you to install their malware thinking it is a

    protection against malware.

5. Some of the anti-malware products on the market are worse than the malware

    from which they purport to protect you.

6. Be cautious where you go on the internet.

7. Only download anything from sites you know are safe.

8. Avoid links you receive in email, always be suspicious even if you get something

    you think is from a friend, but you were not expecting.

9. If there is any question in your mind, then assume it is malware.

I had the same exact problem. I had never downloaded anything related to Mackeeper (as far as I know) and http://malwaretips.com/blogs/remove-mac-os-x-virus/ was a lifesaver!

So yes, these are all great suggestions, but no one really mentions possible DNS attacks on the user's local network....

I was constantly being bombarded with stupid MacKeeper Popups and other crazy **** for about a year now on all my devices. Even my cellular devices were acting funny with redirects to the app store and etc. Every so often I would try to look into it by reading forms like this; thus trying all presented options, but yet nothing worked!

Finally I found out the problem was my router. The DNS servers got hijacked with these malicious IPs:

104.131.237.53

162.243.157.142

Removed them from my static DNS IPs; problem solved .... DOH!

this worked for me was sent by mackeeper support

The Safe Mac's Adware Removal Tool is safe to use. However, since MacKeeper is a scam, in general you should not trust anything its representatives, or the reps for any other scam product tell you. Also note that TSM's tool is no longer receiving updates, and it recently launched AdwareMedic: http://adwaremedic.com.
