Have NOD32 on a Win2k SP4 box w 512MB ram. This evening I noticed that the Control Center was NOT in the systray! Looking at the logfiles there is an entry in the event log at 7:50:15 for the 20060426 definintions. The next entry is at 18:50 when I restarted the control center and it updated definitions to 20060427. It is really unnerving to see the control center disappearing like this especially when NOD32 is password protected!
