Annoying worm problem

Well, it seems I have a worm on my computer. Unfortunately, it looks like a doozy, because only one program (that's not even on your list), was able to find it.

The virus: W32/Rbot-EMH (info: http://www.sophos.com/security/analyses/w32rbotemh.html)
located: C:\System Volume Information\_restore{727DD664-9803-4C41-A707-19E3640DBBB4}\RP564\A0632126.exe
Found with: http://www.sophos.com/support/knowledgebase/article/3252.html

What I did:
-I first noticed the problem when my commercial virus scanner (http://www.bsafehome.com/moreinfo.asp?product=264) found some viruses on my computer. It managed to delete all but 1.
-I was then directed to the program mentioned above to get rid of the final virus. It did, but managed to find another problem as well (the one mentioned above). While it was able to delete the infected files it found, the problem still persists, and my guess is that the virus respawned itself through the registry.
-I came to these forums, and followed the list mentioned in the sticky. Not one of the programs found the virus mentioned above, but there were a few minor spyware problems detected. My guess is that virus is somehow tied to the spyware issues, because I didn't have any problems before it appeared.

Symptoms:
-The sound is distorted.
-There are a few antivirus advertisements appearing.
-The taskbar (I think that's what it's called), has disappeared on occasion in normal mode (minimising a program seems to fix this problem), and the whole desktop disappeared once in safe mode.

I will attach the Panda activescan file below. I performed the bitdefender scan, but there was a mistake made and the log file was not saved (it found no problems). I am in the process of running it again, and will post the new log asap, but thought that there might be enough information here to start dealing with this problem.

 

And here is the bdscan file.

 

And here is the HijackThis log.

 

Update: I ran the sophos program again, and it found nothing this time (seems like it deleted the file successfully, but the symptoms still exist).

The major problem is that sounds on my computer sounds are distorted to sound like they are echoing. Could it be that this problem is simply system settings that have not been corrected after the virus was deleted, or is there still something lurking on my hard drive?

 

Sorry about the long wait... Right after posting last, "life" happened to me, and I havn't been able to get enough time to fix the problems until now.

Because it's been a month since my last post, and because the computer had to be used since then out of necessity (even though there was malaware still on it), I went through the entire list on your first page again, just to make sure there were no other problems. I have posted all three scan files again.

Other news:
-The sound problem is gone. You were right, it wasn't a malaware problem!
-Because things have changed by themselves, I did not do the steps you outlined before. As you will see, the lines you told me to remove seem to have removed themselves!

Finally, I find it odd that you didn't see a firewall or antivirus on my machine, because I do have a commercial one installed (albeit, one that is not commonly used).

Thank you so much for helping me with this problem.

 

Thanks for your help!

Here are the files.

 

Thanks again!


My computer is running great now. I do not see any symptoms of viruses! (Note: This has not changed since I got rid of the sound problem as well as the popup problem, even though there were still viruses left on my system!)

 

Thanks a bundle!

I'll be sure to go through that list, and I'm also bookmarking this great site for future notice!
