... a Redditor with the username ArmoredCavalry observed that their router, a TP-Link Archer AX3000, was sending loads of their data to the Avira SafeThings servers. The Redditor says that in 24 hours, more than 80,000 requests were made.
While Avira does say that users will be in control over their devices, the Redditor claims that the service continues to run on its own even though they haven't subscribed to it and all such related options are disabled on their device.
... this behavior was already confirmed earlier by XDA which found that the TP-Link Deco X68 was exhibiting this problem as it was sending out data even when the service was disabled. TP-Link said at the time that a future firmware would fix the issue but XDA was seemingly not made aware of such an event.
