My ISP recently identified a one-time "possible" Flashback Trojan incident using the following agent id: "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0.1; sv:4; id:FFF79A8D-EC94-58C6-BA9C-9BCE5DD45C10) Gecko/20100101 Firefox/9.0.1" ... if Firefox 56.0 (64-bit) is installed on both devices that connect via this ISP WIFI service, to what does the agent id data actually refer ? ...

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0.1; sv:4; id:FFF79A8D-EC94-58C6-BA9C-9BCE5DD45C10) Gecko/20100101 Firefox/9.0.1

It shows running a Mozilla Browser in the series 5 versions NT 6.1 = Windows 7 Wow64 is a Windows file The rest of that is RV (revision) 9.0.1 SV no idea Id looks like a registry entry but google turns up nothing. (if ISP found that then could be a serial # to the Firefox but..do not think so and would not help anyways) Gecko is Mozilla and I think the Engine version
