Norton 360, developed by Symantec, is marketed as an "all-in-one" computer security suite. The package includes an antivirus, a personal firewall, a phishing protection program and a backup program. What distinguishes this suite from Norton Internet Security is the inclusion of file backup and PC maintenance capabilities.
The package is distributed as a download, a box copy, or is preinstalled on computers as OEM software. Additional functions, including parental controls and e-mail spam filtering, are available as extensions developed also by Symantec.
Norton 360 is compatible with Windows XP (excluding 64-bit editions), Windows Vista and Windows 7.
Version 2.0 was released March 3, 2008. The backup feature can now inscribe data to Blu-ray and HD DVD discs. Multiple installations of Norton 360 can also to a centralized location. When backing up files online, the user can control the amount of bandwidth Norton uses. A registry cleaner is bundled with the PC maintenance tools, allowing the user to remove invalid entries. Phishing protection for Firefox was added. Supplementing the phishing protection is the Norton Identity Safe, which stores login credentials to websites. A network map allows users to view the status of other Norton installations on networked computers and view basic information about each computer. System requirements remain the same as version 1.0.
PC Magazine found the spam filter to be weak, misidentifying over 25 percent of valid e-mail as spam. CNET encountered problems when installing version 2.0 on legacy machines.
