Although I cannot be sure about this I think in this case
it may be a false positive, netspy is a commercial
keylogger that has to be manually installed so if you
know its not on your system I think it may be safe to
leave that in place.
For netspy you can check in the system32 folder
C:\Winnt\System32 (Windows NT/2000)
C:\Windows\System (Windows 95/98/Me)
C:\Windows\System32 (Windows XP)
for a file called Nsutil.exe if found double click then
choose Remove NetSpy.
You can read more about them from here

To be sure of this there is a couple of things you can do
First is contact the producers of the keyboard & mouse
and ask them if they include kbhook.dll and for what
reason.

Second is to find the kbhook.dll file on your system and
upload it at a virus scan site and see if that gives a
infected reading after the scan
You can upload them at many sites but here's 2 of the
main ones that use various scanners
