Pop-ups, Possibly Vundo?

I was wondering if someone can help me with this problem? The other day I started getting random pop-ups and so I did my usual thing: run Ad-Aware, run HijackThis, rooting through my windows/system32 file to try to see if there were any weird-looking .exe or .dll files that are sitting in there. What I usually do is just run a check against anything I don't recognize through Google to see if it's legit or something weird. This time around, I got a bunch of seemingly random named files that don't show up on Google at all, but are always marked as "DLL Running" in HijackThis. HijackThis doesn't seem to do much to the file and I have been using Dr Delete to get rid of it (if I just try to delete it regularily, Windows tells me that some application is using the file so I can't delete it).

I thought I got rid of the problem and that was two days ago? I'm still getting pop-ups. If I don't touch it usually, I'll get a pop-up every hour or so, and that's it? The annoyingest thing though, is that I can't leave my computer on standby because it seems that whenever a pop-up decides to go up, my computer will just go out of Sleep Mode just to accomodate said annoying pop-up. Since then I've done more research on it and I think it's Vundo, and VundoFix seems to do stuff for it but never gets rid of the problem. It targets some of the files that I can see in system32, but not all of them, so I am wondering if there is some sort of generating source that I haven't caught yet? Or because it is not getting rid of all of the files at once the other ones just replicate more and more weird .dll files? Since I started running VundoFix also, the number of rogue-looking .dll files have increased. I found this board over Google with logs of others having the same sort of problems, but I'm a little scared to do any more without personal guidance!

Much appreciated if anyone could help!

Try this :

* Double-click SUPERAntiSypware.exe and use the default settings for installation.
* An icon will be created on your desktop. Double-click that icon to launch the program.
* If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Udates". (If you encounter any problems while downloading the updates, manually download and unzip them from here.)
* When done, select "Scan for Harmful Software".
* There are three scanning options. Choose "Perform Complete Scan" and click "Next".
* When done, a Scan Summary will appear with potentially harmful items that were detected. Click "OK".

Some .dll files (small programs dynamically linked with larger programs that uses them during program execution rather than being compiled with the main program) are locked and considered as in use by another program so they cannot be deleted easily. The first thing to try is delete the file while in "SAFE MODE".

However, if you have a vundo infection, Vundofix may not be finding all the bad files. If your still having problems after doing as fozzie suggested, run Hiajckthis and post your log in the HijackThis Logs and Analysis Forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.
