How do I uninstall Opera, once and for all?
I keep following the directions for Windows 8 to uninstall, and it keeps coming back every few days. I'm happy with my current systems, and it's creepy to have this thing installing itself and keeping me from accessing the uninstall program.
You don't happen to use Vipre antivirus (especially it's Auto Patch Update Software tool), do you? See this thread: https://forums.opera.com/topic/4066/unwanted-download-and-install/30
