It makes you feel safe. I'm having big trouble with a false positive. It is detecting an app I developed as malware and it is not. There is no way I could make Norton ignore my app and the notifications are very invasive about the malware. I need to keep using the app for my work, I can't uninstall. I contacted Norton and they didn't offered a rational help. They asked me for the app (I won't give it to them) when I just need if for Norton to allow me to ignore the problem.
