Windows PC Backup Wizard Setup - good or bad?

One of my clients recently started getting a popup on her Windows 7 computer with the text: "Critical Alert, activate windows, backup now!". You can click 'Cancel' to close the popup or 'OK' which opens another box (see attached picture) with the following text: "Windows PC Backup Wizard Setup, Unlimited Free PC Backup, Protect your documents, folders, movies, videos, pictures and more, automatically!". It asks to enter your Name, E-mail, and Password (which we did not do). There seems to be no way to close this box except by logging out of the user account (it's not in the Task Manager applications list). I am thinking this has to be a malware/bad program since there is no way to close it. I ran a malwarebytes scan but we're still getting the pop-up. I tried searching online for somebody else who received this popup but couldn't find anything. I need to get rid of this somehow and would really appreciate your help.

Thank you,
Bob

I appears to be a Carbonite Online Backup Software. See if it's listed in Windows Programs and Features and you're able to uninstall it.

If not, then you might have to manually delete. Instructions can be found here...

Could you post the website you found this Windows PC Backup Wizard?

It just pops up randomly, not when visiting any website.

You haven't mentioned if there is anything related in programs and features or if you tried AdwCleaner.

AdwCleaner Download

It's definitely unwanted behavior.
