i have some registry entries i see using jv16 power tools im not sure about and i have read that one is spyware but i just want to get the professionals advice/opinion as to what these belong to:

HKEY_LOCAL_MACHINE\Software\C07ft5Y\WinXP

HKEY_CURRENT_USER\Software\Cygnus Solutions\Cygwin

HKEY_LOCAL_MACHINE\Software\Gemplus\Cryptography

HKEY_LOCAL_MACHINE\Software\Schlumberger\Smart Cards And Terminals

and occasionaly, an entry called NoTreat shows up, even after i remove it. it isnt in there now, but i havea feeling it will come back.

any ideas as to what these are? thanx in advance
