safety and the stability of a given file. I.e. if a file was stable on Windows 7, but unstable on Windows XP, XP users would be notified of the file's instability. Enhanced removal tools were tightly integrated for better cleanup of infected systems. Once triggered, the new, more powerful version of Norton Power Eraser restarted the system to locate and remove fake antivirus software and other deeply embedded threats that were otherwise hard to remove. A new tool called Norton Management helped manage different computers and devices from a single location. Other changes included SONAR 4, Google Chrome compatibility for Identity Safe and Safe Web and the ability to store passwords and notes in the cloud. However, the License Agreement did not guarantee passwords were stored securely and provided no remedy if the cloud vault was compromised. The user interface was simplified to use only three buttons.

The CPU meter that was removed from Norton 2011, returned (only on the "advanced screen").
