How to remove MacKeeper virus from Mac [July 2019 upd.]


Find out why many users consider MacKeeper to be a potentially unwanted application and learn how to completely uninstall MacKeeper from Mac in a few steps.

When it comes to keeping one’s Mac computer safe and performing at its peak, there are quite a few effective solutions out there as well as impostor apps that pass themselves off as ultimate, all-in-one security and optimization suites. It’s might be difficult to state outright whether MacKeeper is the former or the latter type, but there is a great deal of user feedback that doesn’t play into its publisher’s hands. People have been complaining of shady promotion mechanisms, where they are redirected to what’s called landing pages that highly recommend them to download and install MacKeeper and have it clean up and secure their Macs instantly. This questionably ethical marketing also involves annoying popup ads that accompany users’ web surfing and report numerous issues. Such an atrocious malvertising literally coerces the targets into installing the program.

All in all, the distribution facet of MacKeeper is amongst the biggest issues accompanying this utility, but not the only one. Upon making its way into a Mac, often without even asking for user authorization in a clear way, the app continues to shell the admin with noxious error reports as well as popup dialogs about poor performance and security problems. The motivation for conducting this brainwashing campaign is to persuade the user to register the full licensed edition of the program. Note that some issues reported by MacKeeper may actually be there, but the way it presents this information does not fit in the paradigm of legit software activity.

To top it all off, MacKeeper runs system scans at random. The scan results are, predictably enough, disconcerting and have a flavor of pressure upon the victim. It purports to detect hundreds of megabytes of junk on the machine, spyware or other perpetrating code, and critical performance issues. Simply closing the graphical interface to get those scary results out of sight will be a short-lived relief, because popup alerts will continue to bombard the user with recommendations to apply a fix, a paid one of course. Yet another flip side of MacKeeper’s activity is that it may have a conspicuous system footprint. Therefore, the Mac will run slower than usual. Furthermore, this application may install rogue browser add-ons on its own, that is, without asking for admin’s consent.

To recap, this utility may create a delusively good impression of a handy tool accommodating useful functionality, such as Mac cleanup and protection modules. And yet, it isn’t the most unobtrusive app imaginable, to put it mildly. The myriads of irritating popup alerts are likely to make user experience go down the drain. If MacKeeper is on board your Mac and you are unwilling to endure its activity any longer, follow the steps below to uninstall it. Before getting down to removal, though, be sure to undo some changes that you may have made to your data using this program. These include file encryption and backup. An extra tip is to refrain from installing any apps pushed by fishy online ads.
