I am sure I am infected with the Vundo Trojan. I am getting popups while using internet explorer and every now and then Norton 360 tells me that it is removing Vundo. But I don't think it gets the job done. I would greatly appreciate it if someone could help me troubleshoot my system, thank you.




This computer recently experienced the Blue Screen of Death, and I managed to restore Windows back to the way it was but unfortunatly I could not restore it back to before I had the infection. I have had a Vundo and Virtumonde infection. I have tried the vundofix.exe and virtumondefix but it has not worked.. I recently installed Norton 360, and it caught some of the vundo problem, but I am still getting popups for reditty.com and other websites. I am running Windows XP Home Edition. I used to get a lot of DLL errors but have managed to repair the system to a point that I am not recieveing those errors anymore, but I know that there is still something, vundo or other, on this system.

It appears that the popups have stopped. I surfed around a little and no popups. I tried a lot of things before I came to this site for help. You did a great job. Thank you very much for your help.

Now 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.
