I have found two that I can safely recommend to anyone:

Norton 360 2.0

Eset Nod 32 securty

Norton is a bit easier to set up so that it takes care of everything without bothering the user with questions on how to deal with issues.

You might also give Symantec Endpoint Protection a look too. It's pretty streamlined and takes care of everything.

I can't help you on the language question as i have never looked into that.
