Hello Bleeping Computer:

After much frustration with the "get-answers-fast" redirect, I decided to see if there was some way I could remove the issue and was referred to the 'Bleeping Computer' forum. Not realizing that I first needed a 'helper' to assist with the supervised running of ComboFix, I went ahead and let it do its thing. After it completed, the computer rebooted itself and it was then that I recognized that I could no longer access the Internet.

1. I tried IPCONFIG and ran 'repair' on the wireless connection wizard and still nothing. The message I get is:

"Windows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address.
For assistance, contact the person who manages your network."

When I use the Internet Explorer "Diagnose Connection Problems" button, the message I keep getting is:

"Windows has detected a problem with the Winsock provider catalog on this computer. This catalog allows programs to communicate with this computer across the network. Would you like Windows to reset the catalog to the default configuration?"

I select "Yes", the computer restarts, and nothing changes. Ugh.

It looks like ComboFix successfully removed the 'Zero-Access' malware/rootkit issue -- but now I can't access the Internet anymore. This is a bigger problem than I think I started with!

Now I'm on my other computer trying to figure out what happend and how to solve it. This is really awful. Has anyone had this problem before? Any bright ideas or help with this would be muchly appreciated.

(ComboFix did say it created a .txt log, but I'm not able to send it from a computer that is unable to access the internet).

Thanks so much for taking the time to read this.

Hi,

This can be a side-effect of removing Zero Access, but we should be able to get you back up and running.

I'd like to see the ComboFix log, so let's transfer that over to your clean PC and post it here. Let's do it safely, just in case your PC is still infected (we wouldn't want you infecting your clean PC).

You will need an empty flash/USB drive.

On your clean PC
Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.

Now you can plug your drive into your infected PC without the worry of the drive becoming infected. Navigate to C:\ComboFix.txt and copy it to your drive, then copy that to your clean PC and upload.

Casey
