I recently made the mistake of downloading what I thougt was Active X. Since then, I've had various infections. I have Adware and SpyBot. I've updated and run both. I also ran SDFix.

Last night, SpyBot found Virtmonde and Virtmonde.dll. It said that it fixed them. I read one a thread that said even though SpyBot said it fixed the problem it really didn't. So I plan on running VundoFix and ComboFix tonight. Does this sound correct?

After the infection, my screensave is now a bunch of bugs that appear to be chewing away at my screen. This is cute, but not what I want. I change my screensaver, but that did not fix the problem. How can I get rid of this screensaver? Is it doing more than just screen saving? How can I identify what it is and where it is?

I get popup messages from SpyBot saying that it has detected a change in the registry, and asks if I would like to allow or deny. I have been denying. The entry is for SpyBotDeletingB6456. Have you heard of this? There are other names as well, but I don't have them infront of me.

Thanks for your help!

C.I.

Please note the message text in blue at the top of this forum.

You should not be using Combofix unless instructed to do so by a Malware Removal Expert.

  • Click the Scan for Vundo button.
  • Once it's done scanning, click the 'Fix Vundo' button.
  • After running VundoFix, a text file named vundofix.txt will automatically be saved to the root of the system drive, usually at C:\vundofix.txt.
  • Please copy & paste the contents of that text file into your next reply.

When I got home, I booted my desktop. Spybot automatically started so I let it run. I'm not sure why it started automatically, I usually have to manually start it. Anyway, Spybot found Virtumonde.dll. I fixed it with Spybot.

I then ran Vundofix. It found no issues so I don't have a log to post here.

I then ran MBAM and it found 24 issues. I fixed those and rebooted. Here is the MBAM log:

-----
Also after rebooting, I got a pop-up box from Spybot which indicated it found an "important registry entry that has been changed". The entry name was "SpybotDeletingC1031" and the old data is "cmd /C del 'C:\windows\system32\iifgFXN". I just ignored this and turned off the computer. What else should I do?

Thanks very much for your help!!

How is your computer running now? Any more reports/signs of infection?

I'm still getting Spybot messages saying that a registry entry has changed. The category is "System Startup global entry". The change is "Value deleted". The entry is "SpybotDeletingC1031". The old data is "cmd /c del 'C:\WINDOWS\system32\iifgFXN". It is asking to allow or deny change. When I click deny, I get another Spybot pop-up like the previous, but with a different entry and old data.

The second entry is Spybot - Search_Destry and the old data is "C\Program Files\Spybot - Search_Destroy\SpybotSD.exe" /autocheck. When I denied this one I got a third pop-up with a different entry and old data listed.

When I denied the third one, I did not get any others. Before I was getting about 17.

Is denying the change the correct response?

Other than that, it looks good.

Thanks for your help!!

/autocheck is a command line parameter to start scanning immediately. Read here for more information about the various command line parameters.

Read here for more information about a manual vs a auto scan.

SpybotDeletingC1031 is a RunOnce command to delete iifgFXN which I can find no information on so I suspect it was bad and would have allowed the change.

As long as you use the Teatimer feature you are going to get alerts whenever there is a registry change to the system. If you selected deny change but keep getting the alert, then something is attempting to alter the registry and the pop-up notifications will continue.

TeaTimer alerts which show allowed or denied values are intended to remind you which registry changes are blocked. Spybot-S&D creates logs of TeaTimer's activity and stores them in the C:\Documents and Settings\All Users\Application Data\Spybot - Search & Destroy\ folder. See here. To stop the alerts, follow the instructions in How to Disable TeaTimer.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
