Upon further review when doing a lookup in DXKeeper I get Callbook Error: Not connected to Pathfinder. Is this related?
+ If you're anti-malware application can decide to spontaneously damage Commander, it can decide to spontaneously damage any of your DXLab applications.
+ As a diagnostic step, boot Windows into "Safe mode with networking". Start DXKeeper and Pathfinder. Can you now perform callbook lookups?
