Within minutes, maybe even seconds, of scanning and cleaning w/ spybot, 5 DSO exploit entries (all registry changes) keep showing up even though the cleans are successful. Should I be worried? I scan w/ ad-aware, spybot, cwshreader. Here's my HJT log:

Actually, disregard that advice. Are you talking about the DSO that shows up in spybot? That is just a bug that is being worked on.

You see, there are several reports of this issue here in the Spybot forum, which shows that it is happening for a lot of people, so in that sense it's normal - meaning your system is reacting like many others...

However, the fact that Spybot isn't properly fixing this is just a simple bug that I'm sure will be fixed soon.

Basically what's happening is that Spybot is finding that the security setting for "Download unsigned ActiveX controls" for the (normally) hidden "My Computer" zone in Internet Explorer is not set to disabled.

Given that anyone who is properly patched (via Windows Update) is not vulnerable to this exploit anymore, this is really not a serious issue, so provided your system is patched, you have nothing to worry about and can just ignore this until the fix comes out.


So just put them on *Ignore*

Also, Please don't PM me your hijack logs. I would you rather post them and PM me if you wish for me to look at them. A PM with a hijacklog will get ignored!
