Just a little info on that file :
Spybot MUST be installed before this update to work properly.
The DSO Exploit is a security gap in IE. Microsoft did already repair this, so if you have all Windows updates and patches installed, it will not be dangerous for your system. Spybot S&D will still find it, because it contains an invalid value. Spybot S&D just has to reset that value. Unfortunately, in the current version, it sets again an incorrect value, so it is found in the next scan. Please update your main program.
