The message includes: "This can occur if the system clock has been set forward ...". I did set the system clock forward a few seconds to match my atomic clock time. I have since set it back. However, nothing including installing the latest version of ZoneAlarm Security Suite 9.3.037.000 and updating Anti-virus/Anti-spyware has made any difference. I have tried to reset Anti-virus/Anti-spyware from Off to On, but cannot reset it. The overview screen has a fixit button. When I click on it, it appears to be doing something, but comes back and says that "Antivirus isn't properly set."
How can I get Anti-virus/Anti-spyware working again?
