An engineer from Newaygo County who helped stop a worldwide cyber attack over the weekend is urging businesses and organizations to keep their security software up to date.

Darien Huss lives in Fremont and works for Proofpoint Inc, a cyber security company. He found the "kill switch" in the malware used to carry out the global cyber attack that has affected 200-thousand organizations.

Despite the work, experts say the problem may become bigger today when people switch on their computers.
