When I restarted my computer Windows Security Center said I had no antivirus/firewall. Sure enough NIS 2010 was disabled. Reason: It was not verified, although I subscribed 30 days ago. I verify, put in my code, everything is fine. I’ve restarted my computer today several times, each time NIS needs to be reactivated. Ran quickscan: okay. Ran ScanDisk: okay. What is it?
