google.no is an official domain owned by Google. Of course, they're the best out there. Safe site and trusted sources for me. Be aware of the ad results. I wish there were better ways to contact the customer support/help/feedback team.
Google is exactly what you think it is, and it is exactly as "safe" as the people working there are, remember nothing is really actually totally "safe" online anymore...never was to begin with. This is as good as it will ever get, it goes downhill from here, the world turned internet into big brother, free porn and violence for every child alive...the world meaning the powers that be. Enjoy :)
WARNING: If Google is so wonderful and trustworthy, why is it that they track virtually my entire activity on the web? I don't recall them asking my permission. If you value your privacy on the internet, stay away from Google.
