>> 1. Real Time Protection .... Should I use the HIPS ?
From the "Support & Help" section it says this with regards the HIPS setting.
What is HIPS?HIPS, short for Host Intrusion Prevention System, is a system of real-time protection that analyzes the behavior of unknown applications rather than relying on a system of definitions to determine if a file is safe or malicious.
After enabling HIPS, Spyware Terminator creates a database of executable files on the local hard disk. After this database is created and the HIPS function is activated, any attempt by an unknown application or library to install is analyzed behaviorally. If its behavior cannot be determined as being safe, Spyware Terminator will display a warning.
So to me it sounds at it could be a good thing to enable it.

2. As per Kitz's' reply.
Although, I just selected a file for Quarantine, but afterwards it does not show up in the quarantine folder (even after a restart of the program), and with a subsequent scan it still came back showing again.
But in your case these two files sound like registry errors, so a clean of the registry should sort them out.
