F-Secure Gatekeeper = "nwbkgw.exe"

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\RunServices
F-Secure Gatekeeper = "nwbkgw.exe"

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Run
F-Secure Gatekeeper = "nwbkgw.exe"

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\RunServices
F-Secure Gatekeeper = "nwbkgw.exe"
