Mackeeper

It won't uninstall. I think it might be a disguised virus.

It's not a virus although some folks would tell you that it's worse than a virus! Follow these instructions to completely uninstall Mackeeper.

In general, I make it a practice of not installing ANY administrative third-party software on my MAC. This goes for Mackeeper, Onyx, CleanMyMac, etc.

I spent many years as a Windows user from the 3.1 days in the early 80's and now use Win10 on my MP using Parallels. I never saw any 3rd party software that was worth a thimble of spit when it came to protecting, cleaning, etc, with two exceptions: a good antivirus program such as Norton; a good defragger such as Diskeeper. I many times found myself helping Windows people dig themselves out from under this utility or that, many times one on top of the other until their machines virtually stopped and had to be restored from scratch.

Mac OS was continually developed to avoid the need for both of these. It defrags itself and certain people say it won't allow any virus, TROJAN or other malware on board. (Even so, I do still use the latest version of Norton on all three of our Macs now running OS X 10.11.3 and also inside Parallels/Win10.)

So my advice, for what it is worth, if a system utility didn't come from Apple, don't install it and keep your disk utilization below 80% or so.
