Is World of Warcraft safe

Yes, World of Warcraft is safe. There are no virii, trojans, or anything else malicious in it when you download it from the official site. As with any software program, you are partly responsible for your safety when it comes to your password. Never give out your password to anyone...Blizzard employees will never ask for it.

You might want to consider getting an authenticator for your WOW. This will add an additional layer of security to it.
