Fake Safari update

From Malwarebytes Unpacked:

Fake Safari update installs MacKeeper, ZipCloud | Malwarebytes Unpacked

This sounds very nasty.

Quote:

Victims of this malicious installer should immediately remove both MacKeeper and ZipCloud, of course, but should also reinstall OS X. This will overwrite Safari and its support files with fresh copies. It should not be necessary to erase your hard drive, simply reinstall on top of your existing system. Although this should not affect your data, it would nonetheless be wise to back up your computer before starting this process, just in case something goes wrong.
