Humans vs Zombies (2011) on Netflix

Plot summary

A deadly virus passes from person to person through direct contact, and a group of students on summer break is exposed to it. Those it infects end up enslaved to an invading swarm intelligence and hungry for human flesh. The students come home and carry the infection to classmates and to townspeople who have no idea what is coming. One by one more of them fall ill, and the outbreak swells into a horde of zombies. A campus security guard who sees conspiracies everywhere gathers students and guides them out. Together with a few uninfected townspeople, the group goes looking for other survivors and for where the virus came from.
