This is happening on multiple machines.. No config changes made last Friday or over the weekend.. These machines were working, and then came back on + got updates, and then went into a fail mode. I uninstalled, rebooted, and got the same error message. I then went in, and deleted out the NOD32 folder in program files that had my .lic key, and rebooted then it worked. Very odd but I hope it's not a cascading affect all day as others get updates.
