Anti-keylogger
These parameters allow you to tune up DeviceLock’s ability to detect hardware keyloggers and to define what DeviceLock Service should do when a keylogger is found.

Use the shortcut menu available via a right mouse click on every parameter.
The anti-keylogger parameters are as follows:
