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 has been described by various sources as highly invasive malware*that can de-stablize your operating system, adding that it is unethically marketed, with a history of making false advertising claims, by a company called Zeobit, and a rip-off.
May 30, 2012 Apple sells a lite version of MacKeeper called 911 Bundle through the official Mac App Store, which is carefully vetted for malware. Likewise, Cult of Mac does not offer malware through our Deals. Jun 08, 2016 A few months ago I decided to try MacKeeper, a third-party utility software that is advertised to do three things for a Mac running OS X: enhance security, manage data, and optimize performance. An ad for MacKeeper on Apple.com sparked a desire to improve the speed of my laptop that very moment (I had been putting it off), so I opted to learn more. May 13, 2012 MacKeeper is an award-winning all-in-one system utility that includes 16 powerful maintenance features that fully optimizes, protects, controls, and cleans your Mac.

There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac will NOT be infected by a virus, it may have other security-related problem, but more likely a technical problem unrelated to any malware threat.
