The differences between Norton 360 and Internet Security are that the former has some additional features, including start-up management, automatic data backup and restore, and automatic PC maintenance. Unlike Norton Internet Security, Norton 360 also quickens the start-up time of the computer to improve its performance.
Both Norton Internet Security and 360 have anti-spyware and antivirus software that protect the computer from dangerous software. Both also offer protection against bulk or junk emails from dubious senders, block uninvited connections from other systems and issue a warning if an attempt is made to access an illegitimate website. In addition, 360 and Internet Security have a parental control feature and provide storage for passwords and usernames in cloud space.
However, Norton 360 has some additional features that are not present in Internet Security. Norton 360 de-clutters additional files from the hard drive to ensure optimum system performance. These additional temporary files may be generated by the operating system or while surfing the web.
Norton 360 can also stop an occasionally-used start-up program from running to hasten the boot time. It monitors the performance of the computer and fixes any issues that affect its smooth running automatically. Finally, 360 regularly backs-up the hard drive to make data secure. It also backs-up for optical drives and external hard drives, and has online backup of 2GB capacity.
