Case Study: California Department of Consumer Affairs stops recurring zero-day malware infections and eradicates 99% of threats with Malwarebytes

California Department of Consumer Affairs prevents zero-day malware attacks

The California Department of Consumer Affairs (DCA), a state agency that licenses professionals and protects consumers, was struggling with recurring zero‑day malware infections across its 2,900 desktops and mobile devices. Despite layered defenses (McAfee, FireEye, Trend Micro TippingPoint, firewalls, proxy and email gateway), unexplained network activity repeatedly forced IT to re-image up to 10 machines a day and pulled staff away from other projects.

DCA deployed Malwarebytes Anti‑Malware for Business, which quickly uncovered and blocked threats other tools missed; the agency eradicated 99% of malware problems, eliminated daily re‑imaging, and stopped recurring infections. With the Malwarebytes Management Console and hands‑free protection, IT now schedules weekly scans, traces infection sources to prevent spread, and has reclaimed staff time for strategic work.
