About the DSO Exploits, the following is from Spybot.
"The problem with the DSO Exploit is a little bug. We have already been able to locate and fix it, but unfortunately it was not included with the last update. It will hopefully be with the next one. 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. As explained before, we corrected this but have not commited the update yet."
