If you don't trust the link, just google the site (www.tutvid.com) and it Will appear, meaning it's safe. I only once bumped into a not so safe site via google, and that was the pirate bay, a very well-known game-torrent site if i'm right. if you still don't believe me, just go check out tutvid's youtube channel. he has flash tutorials. the link is safe. if the domain is safe, surely why would he put a virus in a subdomain? nobody would. trusting tutvid therefore means trusting the link, and tutvid is Safe. just ask google and its little baby brother youtube.
