After running Filemon and Regmon, Sygate 5.5 Pro (smc.exe) constantly accesses the registry and the files seclog.log and cmondll.dll which in turn causes explorer.exe to query smc.exe. cmondll.dll does not exist on my hard drive. Is this normal activity of an idle firewall? It's in excess of 500 queries per second which makes for light hard disk usage and noise. Reinstalling didn't do anything.
