Norton antitrack gave me false information

I ran a Smart Scan and Norton told me I had 321 trackers following me.  Which I thought was strange for a new device. Upon uploading the trial and running antitrack, I find out I had ZERO trackers following me!  Is Norton providing customers with false information to get them to buy products they don't need or was it someone else trying to get at my personal information??? I'm even more worried now that I downloaded!
