A simple question but please don’t be too brief. eg: "because its the best" doesn’t really help.
i personally have used 360 for a year now and haven’t had any infections (i checked that by running scans with mulwarebytes, but it found nothing but a few PUPs) from how i understand its reviews, its for users that don’t use CDs or flash sticks (my usage habits), so the only possible way of getting infected is downloading malware through the internet via). i also hear that Sonar is fantastic, (i don’t like updating signatures all the time so it helps) the browser, which will use more of Norton’s components to verify if a file is safe (such as the cloud based scanning
basically i like Norton’s "practical approach" to how a normal user would become infected. (No normal user will disable Norton protection to willingly install malware, making many independent tests obsolete)
