Vundo variant - XP Police

Running 2 pc home network - my laptop and teenaged daughter's desktop. The only problem I've noticed on the laptop is network connection loss at times which I believe may only have been fault of infected desktop. We've had Trend Micro Internet Security running until end of 2008. There was a problem last year with the desktop: IE was opening up multiple tabs at random times when she would close out of MySpace. I don't know whether she had allowed an install through the antivirus/spyware or not but I had run manual scans and the problem had still returned. I had deleted temp internet files and temp folders (I doubt I found them all) through safe mode and had Trend Micro tech support analyze HJT log and was told it was clean. There was one repeat around the end of last year.
I decided to search other options for security software and had not been available to do it timely. The subscription expired in December and I had only assumed that the desktop would run the same as the laptop: With security software still operational, albeit unable to update for a few weeks. Unfortunately, it was completely disabled on the desktop without me knowing it. It was the network disconnects that had me check out the desktop and realize the problem. Google searches were redirecting to similar sites with 'Star Search' titles and there was a repeating security center pop up insisting that I needed to allow MSAntispyware be enabled to remove found threats.
I had used the 10 software procedures listed in 'Gizmos' site and decided to sign up here for the support forum. The procedures here were not the same and quite specific and time consuming, but I believe it sounded perfectly worthwhile and sensible so I disregarded my other work and followed your Malware Removal Guide in order. I have noticed no malware recognition since finishing up the scans recommended from Gizmos (I believe Bitdefender Online was the last to detect and clean). How much malware was one and the same I am not sure but there were references to a vundo variant and XP Police. Nevertheless, I have gone through your procedures and am attaching logs in these two posts. I realize computers can appear to be clean when they are not. One thing I noticed right now is that a user account seems to be deleted while there still is reference to it when scans listed cookies.
The only thing I added to the list of tasks was required for combofix to run: It was caused by a windows wmi error which believed McAfee was running. (I don't believe it was ever installed on this computer but could have been offered from another program). Through a command prompt, I shut down wmi service and renamed the repository folder before restarting the pc and the service to allow it to be rebuilt. It worked after repeating the procedure and combofix no longer gave the antivirus warning, and security center no longer shows a false McAfee presence. I also uninstalled Trend Micro before starting any cleaning although it still shows up in control panel and I have not yet been successful deleting the folder with a access restricted dll. (I can deal with that later). After completing your guide, I did install Avira to keep a running antivirus although it won't show on these logs. Please let me know if the logs suggest anything wrong.

 

for the mgtools log
They all seem clean to me in contrast to the first time (superantispyware and malwarebytes I had used before finding your malware removal guide). I can send you those first time logs if you wish, but these logs are immediately after following your guide.
