I use your security suite, so I hope it is capturing all the spyware and malware. At any rate, I could see that Netflix on my Firestick used the most at 80 gigs. While I checked several times to see if any unknown devices were sponging off my wifi, I didn't see anything. Then I changed my wifi password on Friday. Now your meter says I only used 1 gig yesterday, which sounds correct. Therefore, I either blocked someone from using my wifi illegally without it being detected by my router software (I don't know how that's possible) or the tech guy who was at my neighbor's house on Friday corrected the hookup. I will continue to monitor the usage to make sure everything is working properly.
