Hello darkster6,

As I've told you in the chatroom (yes, that was me), it certainly is much easier to work the problems out here. So here goes…

SDBot is often installed through Operating System vulnerabilities. I see that you haven't updated to Service Pack 2. I recommend you apply all patches and critical updates, but only once you are fully cleaned!

Let's see if we can get more info and perhaps kill this nasty.

You mentioned running NoAdware and it flagged some entries. I'd like you to see if you can find a log or report in NoAdware and post the relevant info here.

Download this tool and save it somewhere handy but do not run it yet.
http://downloads.andymanchesta.com/RemovalTools/SDFix.zip

You will need to extract the contents of the file using an unzipping utility like winzip.
Once extracted, you will see a file named SDFix.exe. (it is a self extracting exe) just double click it to extract it. You should get a notepad window open up upon doing that with the following text:

The SDFix Folder has been extracted to %systemdrive% - Please run from that location.

(%systemdrive% = drive that contains the Windows directory - typically 'C:\SDFix')

Open the SDFix folder in Safe Mode then double click the RunThis.bat file to
start the fixtool. If run in Normal Mode, options to download and run Anti-Virus
command line scanners are displayed.

Once you have done that, restart the computer in safe mode. To get in safe mode, while the computer is restarting, just after the lights flash on the keyboard and beeping but before the windows loading screen appears tap the F8 key on your keyboard. You should get a menu. Choose to start in safe mode (no networking).

Once the computer has fully booted up, navigate to the SDFix folder that was created by the self-extracting exe as noted above. Typically, this will be C:\SDFix\ and run the "RunThis.bat" file by double clicking it.
Follow the prompts and let it finish. You should get a message to restart the computer.
It may seem slower than normal to restart, this is normal.
Once the script has finished your desktop will finish loading. Once that is done, go in C:\SDFix\ and find the file "Report.txt".

Paste the contents of this file along with a new Hijack This log in a reply here.

Good luck

OK looking better.

You should run ATF-Cleaner. Get it here.

Also, I very strongly advise (again) that you go to http://windowsupdate.microsoft.com/ and install Service Pack 2. Once it is installed, you will want to go back and install ALL Critical Updates and patches.
Failure to do this, would only mean you'd get reinfected as most of those infections come through holes in the Operating System. These patches will protect you.

Before installing SP2, I recommend you flush your restore points as those are most likely infected and untrustworthy. You can do this by turning System Restore off, rebooting and turning it back on, creating a new restore point after that.

To turn it off and on, right-click on "My Computer" - select "Properties". Click the System Restore Tab. Put a check in the "Turn off System Restore on all drives" checkbox and hit apply. Restart the computer. Then go back to the System Restore tab and uncheck it, hit apply. Then go to the System Restore function by going to Start - All Programs - Accessories - System Tools - System Restore and follow the prompts to create a new restore point.

Let us know how you're getting along and if things still look good.
