I remember seeing a movie in a store that I passed up on but am interested in finding again

Title had something to do with "Infection" or "Virus".

Cover had a guy with like a crab arm?

The plot had something to do with a guy trying to find some way to save his child who was mutated by some alien disease, and I think was in government care...

Oh and the kid has tentacles.

(Post edit I never watched it but it was in stores post 2007 and seemed to be featuring a Primarily Caucasian cast)
