I didn't think you were. . . It's a serious question. . . with a legitimate answer. MacKeeper was actually Malware, itself. It used social engineering to get itself on users computers by scaring them. It also offered "free" scans and once it was on your computer, it would then CHARGE you to fix what it claimed it found. . . and it always would find something. Such as it would recommend turning off Apple's Gatekeeper, saying MacKeeper could do a far better job of what Gatekeeper did. Not true. . . because by turning Gatekeeper off, everything could be downloaded onto the Mac. . . so that MacKeeper could poorly check it with an incomplete A/V library. . . or it would replace Apple's solid and safe UNIX utilities with its poor versions that were not automatic nor as complete.
Getting it out of your system was a real pain. . .
thanks for a straightforward non defensive answer, I being a XP user am of course aware of the “security” scams out there, just didn’t see Apple users getting suckered.
