Norton Protection System uses several overlapping layers of protection that work together to stop viruses, spyware and other online attacks. Norton Download Insight warns you if a downloaded file or application is dangerous before you install or run it on your PC. Norton File Insight gives you detailed information about the files found on your PC including where the file came from (the website URL) and if it can be trusted. Norton Pulse Updates run in the background and provide mini updates every 5 to 15 minutes–more frequently than the nearest competitor–for the latest protection against online threats.
