While running a full system scan on my Windows 7-64 bit PC using Norton 360 Multi-User, it upgraded itself without warning or asking permission to the newest version, Norton 360 Premier v22.5.0.124. Since then I've been having several problems on my PC.
First, it made my Cablecard-based Ceton InfiniTV TV Tuner inoperable in Windows Media Center, no longer able to view or record TV programs or update the program guide. In the past whenever I've installed or done a major version upgrade of Norton 360, I've had to open up the Network Map to change some settings (the Ceton card works as a network card). But now the map has been taken out of Norton 360. I've tried manually adding the Ceton card and Cablecard to the firewall, but that's only partly helped, and I still can't use the card. I'm probably going to have to revert to the previous version of N360 as not being able to use this card is a non-starter.
Second, it reverted to a months-old version of my logins in Norton Identity Safe, and I had to restore a more recent backup that I'd luckily made. But it's missing a bunch of recent additions and changes that I'm going to have to manually make now.
Clearly, this product isn't ready for prime time, given the many problems people have been reporting with it, including the way it automatically updates itself without warning or user confirmation. Why Norton sought to rush this Alpha or Beta stage product into release is beyond me. One can only speculate.
