It's not an error is SB. It's an old exploit in IE that it picks up if the update is not installed for SB. Go to www.majorgeeks.com
and download it there.
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.
