Many users will see references to an application called MacKeeper on various web sites and via pop-ups on their browser. Not only is it expensive for what it purports to do (freeware applications that do the same or more are readily available), it can sometimes install itself without the user realising it, and it can be very tricky to get rid of.
MacKeeper can be regarded as highly invasive malware* that can de-stablize your operating system. It is unethically marketed by a company called Zeobit and a rip-off.
Further opinion on it and how to uninstall MacKeeper malware can be read here:
Do NOT download or use the ‘MacKeeper uninstaller’ from the Zeobit site, as this will cause even more damage to your operating system.
This is also worth reading:
Equally phoney was iAntivirus:
until it was purchased recently (May 2012) by Symantic (makers of Norton anti-virus which does not work well with Apple OS X). Even after having tinkered with it, iAntivirus still fails to do the job properly and cannot be recommended.
There are no viruses that can affect Apple OS X and there is therefore no reason to run anti-virus software on a Mac, but a Mac, like all computers, can transmit viruses and malware to other users particularly those running Windows. Note, however, that Trojans are another matter and can represent a genuine threat, an example of which was the recent 'Flashback Trojan' which you can read more about here:

* The expression ‘malware’ is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software.
I knew from the first moment not to download it or even click the OK button on the pop-up. In the course of trying to find a way to get rid of the pop-up, I read Mr. Reed's article and many discussions in the Apple community and elsewhere. I will keep the links for future reference.
Still, I do not have an answer on how to make Safari functional again.
I did not install MacKeeper; I did not even click it's pop-up ad window.
However, it's pop-up has taken over Safari. I cannot use Safari at all. The only Safari window that will display is the MacKeeper pop-up. I could Reset and Quit Safari, but when I reopen it; again, the only window it will display is the pop-up.
Am open to any suggestions to effect a rescue of Safari from the MacKeeper.zeobit pop-up?
Quit Safari (by force if necessary.) Relaunch it by holding down the shift key and clicking its icon in the Dock. That will stop the page from reloading automatically. Select Safari ▹ Preferences ▹ Privacy ▹ Remove all website data to get rid of any cookies or other data left by the server. Open your Downloads folder and delete anything you don't recognize.
Thank you, Linc Davis!
After spending much time reading various discussions, which offered nice tips that were either not available to me (menu items greyed out) or not applicable (since the application was never installed), your directions worked.
Although initially (for 30+ minutes) I could not Force Quit even after powering off; once that option returned, I was yet unable to shake the pop-up when I next opened Safari. But, at least I could Quit or Force Quit when that happened.
I took your advice Remove All Website Data and to delete any unrecognized files in the Downloads folder, going back a a couple months or so. I presume that's enough.
My deepest thanks, Teelbee
PS: I already removed all website data in response to a suggestion earlier on this thread. Didn't help at all. Almost immediately after doing so I got the MacKeeper screen back up again, hijacking Safari.
This only happens in Safari, not Firefox, by the way. I guess I will start using Firefox permanently until Safari can get a restraining order or something against this unscrupulous, low-life company.
And no, I do NOT have that malware, crudware piece of garbage MacKeeper installed on my Mac. Never have, never will. What a bunch of sleazeballs.
What worked for me:
1. Hover mouse over dock area for a few seconds until dock of icons appears. Hold down mouse on Chrome icon and select "New Window" from the pop-up menu. This should open a new tab, restoring the top area of your browser.
2. If you still don't see the Chrome controls at the very top of your screen (apple icon, Chrome, File, Edit, View, etc), hover your mouse over the top of the screen for a few seconds until it appears. Click Chrome > Preferences.
3. In the Preferences page, under Settings (left hand column navigation) under Startup, click on "Open a specific page or set of pages" and then click on "Set Pages" and make google.com your opening page.
4. In Preferences under History, Click "Clear Browsing Data" and go back as far as you remember things working fine (e.g. 1 week). I checked off the following: Clear Browsing History, Delete cookies, Empty the Cache, Clear data from hosted apps, Deauthorize content licenses.
5. Quit Chrome (Chrome > Quit Google Chrome)
5. Restart Chrome
