We have just spent the better part of this weekend repairing from infections with the help of instructions located at Sandiís site inetexplorer.mvps.org, and using Windows Defender, Spybot, Spyware Doctor, and others. The problem was that we could not get Windows updates or change settings to do so, the computer would open multiple sessions of IE, and also redirect to other sites unexpectedly.

Quarantined threats include
Trojan.Virtumode
Trojan.Agent!sd5
Trojan-downloader.vb.awj
Rogue antispyware.virus remover 2008
Adware component toolbars
Application.popcap

I can now update Windows and no longer have IE problems, but we now have the following error upon startup.

RUNDLL Error loading WINNT\system32\gfavfbdn.dll specified module could not be found

I cannot see the effect of this error message, but it is a nuisance. What could be the cause? Thanks for any help.

Hello TWright and welcome to BleepingComputer,

Looks like some malware was left behind. :thumbsup:

1. * Clean your Cache and Cookies in IE:

* Clean your Cache and Cookies in Firefox (In case you also have Firefox installed):
  • Go to Tools > Options.
  • Click Privacy in the menu..
  • Click the Clear now button below.. A new window will popup what to clear.
  • Select all and click the Clear button again.
  • Click OK to close the Options window
* Clean other Temporary files + Recycle bin
  • Go to start > run and type: cleanmgr and click ok.
  • Let it scan your system for files to remove.
  • Make sure Temporary Files, Temporary Internet Files, and Recycle Bin are the only things checked.
  • Press OK to remove them.
2. Please download Malwarebytes' Anti-Malware from Here or Here

Doubleclick mbam-setup.exe to install the application.
  • Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
  • If an update is found, it will download and install the latest version.

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediatly.

3. Restart your computer.

4. Please visit this webpage for instructions for downloading and running ComboFix:

http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Please ensure you read this guide carefully and install the Recovery Console first (not for Windows Vista users !).
The Windows Recovery Console will allow you to boot up into a special recovery mode, in case your computer has a problem after an attempted removal of malware. This allows us to help you. (WinXP SP3 users, please download the appropriate SP2 file, Home or Pro, to install the RC)

In the event you already have Combofix, and you're notified a more current version is available, please download the latest version as described in the tutorial.
It must be saved directly to your desktop.


Note: Make sure not to click ComboFix's window while it's running. That may cause it to stall or freeze.

Please post the log from ComboFix (can also be found as C:\ComboFix.txt) in your next reply. :)

If you have any questions along the way, STOP and ask them before proceeding !!

Greetings,
Thunder
Whatever happens, make believe it was intended to ...
