Also: When Opera is updated/update itself, it create a new subfolder with version number in its directory and keep the previous version "just in case"... As a consequence, software firewalls needs two news rules each time Opera is updated: one for the updated updater (sound silly isn't it ?) and one for the browser... Once Opera is started, lsass.exe wants to connect on Internet (Win7 x64). It never occurs before, and don't occur after. I had Opera installed for years, even if it wasn't my main browser I always found it great. I had tried version 16, 17, 18, then uninstalled for good. If they wanted to kill Opera, that's a success.
