Please provide some advanced options to enable/disable the detection of commercial keyloggers. Perhaps bury the option in advanced settings, with appropriate warnings to leave any commercial keylogger detections unfixed if you are not the PCs owner?

I understand that commercial keyloggers may well have an (all be it, murky) place as a legitimate install. However, their omission provides an opening for non-legitimate keylogging to take place. That is, keylogging with neither the permission of the end-user nor that of the computers owner.

Commercial keyloggers are not the preserve of legitimate users. Like any other software, their use can be abused.
