what is Rainbow Sentinel?

I am wondering why these files are on my system, I found a spanish side, but still don´t know what these entries are for:
(Another side told something about vericut, but this doesn´t help much)

HKLM\SOFTWARE\Rainbow Technologies\
HKLM\SOFTWARE\ntpad
HKLM\SOFTWARE\CLSYSTEM

C:\WINDOWS\SYSTEM32\SYSPRS7.DLL
C:\WINDOWS\SYSTEM32\SYSPRS7.TGZ
C:\WINDOWS\SYSTEM32\LSPRST7.DLL
C:\WINDOWS\SYSTEM32\LSPRST7.TGZ
C:\WINDOWS\SYSTEM32\T0000001.TMP
C:\WINDOWS\SYSTEM32\CLAUTH1.DLL
C:\WINDOWS\SYSTEM32\CLAUTH2.DLL
C:\WINDOWS\SYSTEM32\SSPRS.DLL
C:\WINDOWS\SYSTEM32\SSPRS.TGZ

Why tgz? I don´t have linux installed.. strange isn´t it?

Another strange thing is uWDF.exe and WdfMgr.exe both have the same Hash.

 

do u have a program called CD/DVD Diagnostic?

 

No, but I translated the spanish text from the webside into english and this
vericut stuff as mentioned above is a protection system of software.

This is the translation of the strange webside:

RainBow Sentinel LM is a small "tool" that adds to our programs a complete system of protection based on archives of licenses, periods of evaluation and other mechanisms to avoid an undesired use of software at the time of distributing it (as the use during long periods of time).

So nothing to worry about I guess, but personally I handle those files as annoying stuff
because no installed software told something about such irritating files.
Therefore I erase those entries when I find them, they are damn irritating.
They can easily be misinterpretated as virus. Nasty stuff that should not soil my system. That´s my opinion.
