I've watched the trailer multiple times before but never bothered to take a note of it.

The movie is, I believe, a zombie-comedy, because the newscaster says something like "we're ed" when asked about the situation.

I remember a woman pushing a paraplegic zombie from his wheelchair and people eagerly arming themselves to fight with the fanciest and craziest stuff they could glue together.

Tried the kewords Zombie + comedy + virus and watched some trailers, couldn't find it though.
