(sorry for delay but I'm working during day, and not always with internet connection...)
Well, I tried this:
- unistalled Opera.
-Gone il ocal data folder, and deleted entire Opera folder
I lost all favourites, settings, history and so on... so, I guess EVERYTHING should be deleted and setted as default. But nothing changed.... I still get redirected to russian pages....
Well, by friday I'll be back in Italy, so I'd no check any other options,for a couple of weeks... But I'll be back for sure in next journey, from somewhere around the world!
Thank you, by now....
