ASUS routers send data back to TrendMicro if you use any of the features listed at the top half of the routers web based control panel:
What is also unusual is that every single internet connected device (including Android tablets, phones Linux and/or Windows VM's) have AffirmTrust certificates installed once they are connected to the internet and/or updated.
What brought my attention to this was that on a Windows 7 machine one of these AffirmTrust certificates had the "simple name" of Trend Micro.
When I contacted Trend Micro they claimed that the certificates were there because I had visited their support website but I could see these AffirmTrust certificates populate on a fresh install of Windows after running Windows updates without using the web browser to view any websites at all.
Soon after my contact with Trend Micro the simple name field on the AffirmTrust certificates no longer contains the name of Trend Micro and is now blank.
It was about a month after that when I found the article I linked to in my comments above regarding Trend Micro/ASUS.
Is there ANY device, app, website out there that is NOT monitizing the user and/or gathering "anonymous" usage data?
