Hello,
So sounds like i'm not the first.
I'm snagged on this vundo.gen!R problem.
Nothing in my anti-virus arsenal can deal with it. Windows defender complains about it on bootup. Something is suddenly trying to connect to
the internet (since the infection) even when i'm not connected to any networks. Figure it's better to find out how than to start ripping stuff out.
My box is an HP Pavillion running Vista.
Any suggestions?
THANK YOU IN ADVANCE FOR ANY HELP! :thumbsup:
Cheers,
Micoleao

Vista computers are usually easier to clean, unless you have disabled all protection

Defender leaves a lot to be desired as a security program.

Give MBAM a try

No. Try not. Do... or do not. There is no try.

Well there it is. I concure!!!
That seemed to be painless.
I used the link you sent and it found a ridiculous amount of the vundo trojan and nixed them.
For the record, i usually use spybot S&D, Adaware and AVG, none of which worked for this one.
I still want to scan my machine with them but at least windows defender stopped complaining
on bootup like it was before. Your solution seemed to do the trick. :thumbsup:
Cheers,
micoleao

I did reboot and MBAB seemingly deleted the rest.
However, there is another complaint from Defender today. This appeared while i was running a full MBAB scan.
It's calling it win32/vundo.gen!R. (?)

Please download OTMoveIt2 by OldTimer and save to your Desktop.
  • Double-click on OTMoveIt2.exe to launch the program.
  • Copy the file(s)/folder(s) paths listed below - highlight everything in the quote box and press CTRL+C or right-click and choose Copy.

[kill explorer]
C:\Windows\system32\pmnKEurQ.dll
C:\Windows\system32\khfcaAsq.dll
[start explorer]

  • Return to OTMoveIt2, right-click in the open text box labeled "Paste List of Files/Folders to be Moved" (under the yellow bar) and choose Paste.
  • Click the red MoveIt! button.
  • The list will be processed and the results will be displayed in the right-hand pane.
  • Highlight everything in the Results window (under the green bar), press CTRL+C or right-click, choose Copy, right-click again and Paste it in your next reply.
  • Click Exit when done.
  • A log of the results is automatically created and saved to C:\_OTMoveIt\MovedFiles \mmddyyyy_hhmmss.log <- the date/time the tool was run.
-- Note: If a file or folder cannot be moved immediately you may be asked to reboot your computer in order to finish the move process. If asked to reboot, choose Yes. If not, reboot anyway.

Caution: Be careful of what you copy and paste with this tool. OTMoveIt is a powerful program, designed to move highly persistent files and folders. Not following the directions as instructed or using incorrectly could lead to disastrous problems with your operating system.


Rescan again with MBAM, click the Logs tab and copy/paste the contents of the new report in your next reply.

btw,
After my post yesterday i recognized that Defender was displaying the results from the last scan which was earlier than the MBAM
cleanup. I jumped the new hurdles anyway with the new software you mentioned.
Here's the new scan results.
Looks clean to me. In fact, those .dlls weren't found by the MoveIt software.
Thanks for the help. Is there any follow up from here?

You're welcome.

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. Then use Disk Cleanup to remove all but the most recently created Restore Point.

Tips to protect yourself against malware and reduce the potential for re-infection, be sure to read:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Best Practices - Internet Safety for 2008".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".

• Avoid online gaming sites and peer-to-peer (P2P) or file sharing programs as they are a security risk which can make your system susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans target and spread across P2P files sharing networks and gaming sites. In some instances the infection may cause so much damage to your system that recovery is not possible and the only option is to wipe your drive, reformat and reinstall the OS. The best way to reduce the risk of infection is to avoid gaming sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.
