I would hope Symantec would recommend their own software. Norton typically is 4 or 5 in the top 10 (middle of the road). PC Magazine did rate them #3, so that is an improvement. Kaspersky consistently ranks higher and did so in the PC Magazine review (#2).
I was surprised to learn that Norton’s first offering for Windows 10 would not protect a user’s web browsing if they used Firefox or Chrome. I never liked Norton because it was excessively bloated and hurt PC resources.
That was Norton Internet Security. They did roll out an update that includes protections in Chrome and Firefox under Windows 10.
