Interesting movie:

Dragon Day 2013

When out-of-work engineer Duke Evans and his family try to rebuild their lives in a remote mountain town, their own version of the American Dream is cut short on the day a devastating cyberattack destroys the U.S. as we know it. Every microchip 'Made in China' has been infected with a virus that rapidly shuts down all modern technology. The aftermath happens fast, and as the rule of law, water, and food run out, Duke and his family must use all their wits and the unlikely help of Alonso, an illegal immigrant, to survive this frighteningly realistic scenario.
