I reckon you could be talking about "Phantoms", but blurring some detail...there is a scene a bit like that towards the end, bio-hazard suits and all.
The entity itself isn't human, but makes use of a human hosts/messengers.

I saw the trailer and it was not it I am sorry. The monster in the movie I am trying to find looks like those in "The Hills Have Eyes".. sort of, and he is balled as well.

Like I said, this was a long shot! I didn't really expect anyone to figure the movie out based on so little information! But I had to try at least. Thank you guys!

Is this the monster?

could be, yes! don't remember the hair though or it taking place in what seems to be a forest? who is that? thank you very much!

He's from the Wrong Turn movies. Those might be too recent though.
