Hello,
maybe SpyShelter has a diagnostic log of some sort. As I wrote in a previous post I’m not a SpyShelter user so I don’t know if such a log does exist.
Also if some SpyShelter file became corrupted maybe a complete uninstall / reinstall of it could solve your issue. If you choose to do that be sure to export your SpyShelter settings / rules to a file, provided that SpyShelter has an option to do so. A year and a half ago I suggested to implement this feature but I don’t know if SpyShelter team did it in a subsequent release. Option to backup rules and settings
