MacKeeper seems to be the biggest threat to Mac users. How is MacKeeper legally allowed to exist. How can we get rid of it?

Question

At least once a day I get a MacKeeper Pop-up that won's allow me to continue browsing unless I click close the MacKeeper page. Once I do that, a second window pops up that I need to verify that I want to leave the page. I cannot continue using safari unless I click this other window, which I am too worried to do, so I just quit safari, but this window is so intrusive, it stays open even after safari is closed! How is that even allowed to happen and how is that legal. I then have to force quit Safari and restart it. Then if I am looking to buy or download software, half the time the link to the software or the download icon is fake and simply redirects you to  MacKeeper's home page, which again they won't allow you to leave. I have also been told that MacKeeper has planted writers in forums and bloggers and proffesional reviewers all over. Then I hear that the package MacKeeper offers is all software that is available elsewhere for free and it has just been renamed, and the rest of the software is inoperable. How is this company allowed to exist. How could their practices possibly be considered legal?
Is there anything legitamate they offer?mWhat can be done about them???

Answer 1

i guess what i'm really asking is- has mackeeper compromised my computer? and how can i check?
If you did not actually install MacKeeper, it can do nothing to your Mac. I'll assume that the only problems you're faced with have been the intrusive advertisements.
First go to Safari's Preferences and block popup windows: Safari menu > Preferences > Security > select "Block popup windows".
Then, make sure you don't have any Safari Extensions you don't want: Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Then, consider the possibility that your wireless router has been "hacked", a recent problem that has been growing in popularity:If the wireless router you are using is one that uses a web page for configuration, such as Linksys and Netgear products do, it is possible that its DNS settings have been maliciously tampered with. To fix it will require resetting your router using its hardware reset option, followed by configuring it again.
When doing so, be sure to select the option to prevent setup over its WAN port. Different routers use different terminology for remote administration, so be sure to find the correct setting and disable that option. Use WPA / WPA2 encryption and a reasonably secure wireless network password.
btw, it is not on pirate sights or xxx sites that i encounter mac keeper, but baseball blogs and stat sights, and the administrators DO say what you said they would... that they have a third party that pays them to do the advertisments. i know some of these guys personally, and none of them would allow this to happen if they could avoid it. they don't have the most traffic in the world, so they don't have the luxury of choosing where or how they get their revenue, they're just happy they can make a living.
I understand that and I don't begrudge anyone legitimate means of earning a living. However, I strongly disagree with taking the easy way out, saying they have no control over the ads that appear on their site. Would they adopt that stance if their site hosted advertisements for child pørnography?
Somewhere between that extreme (and illegal) example and having no advertisements whatsoever lies responsibility. Your friends should fire AdChoices or AdSense or whatever service is placing paid content on their web pages, and be abundantly clear about the reason. You don't see MacKeeper or CleanMyMac or similar ads for garbage products on many respectable websites. Unfortunately, they appear on enough of them to be the invasive problem it has become. Until enough site administrators stand up and say they're not willing to tolerate it, the scourge of garbage products will continue to result in lost time, money, irreplaceable data, or all three. MacKeeper alone has earned at least $18 million in revenue, by their own admission, and that was some time ago. If all that money does is to enrich one or two people, that's bad enough. How do they know the revenue is not being directed to fund more sinister purposes? How does anyone?
What is the baseball site's URL? Post it here. I want to determine what cookies it drops on the system I'm using.
