While browsing in Safari in a MacBook Pro, a popup for MacKeeper appeared, and my wife was then unable to navigate to websites such as CNN.  Is MacKeeper a scam or a virus?

MacKeeper is a PUP (Potentially Unwanted Program). It's almost as bad as malware.

Force Quit Safari ( command + option + esc keys).Then restart Safari holding the Shift key. If you still have problems Empty Caches (Safari menu > Preferences > Privacy > Remove all website data. (This will also remove history if you do not want to remove History open Safari Preferences > Advanced and check mark “Show Develop Menu” then choose “Empty Caches” from Develop Menu ) If the problem persists download and run MalwareBytes. Malwarebytes was developed by one of our own colleagues here in ASC. It gets rave reviews and is about the most proven anti-malware software for Mac.

It is as bad as Malware.
