Hello.

Here is the link to my post yesterday which is more or less the same info here:
http://www.bleepingcomputer.com/forums/topic427153.html

I am having a problem with a Windows XP Home computer. It was infected with malware and Trojans. I believe I got the infection cleaned up, but maybe not. Now the computer will access the Internet, via Mozilla Firefox and IE7, it will do Windows Updates, and it will update Microsoft Security Essentials, Super Anti-spyware, and SpyBot. It will not update MalwareBytes, Adaware, and it will not map drives. I get these errors:

MalwareBytes:
Update failed. Make sure you are connected to the Internet and your firewall is set to allow Malwarebytesí Anti-Malware to access the internet.

Adaware (I just tried this out of curiosity when Malwarebytes didnít update)
No connection to download Server. Check Internet Connection

Map Drives:
The drive could not be mapped because no network was found.


The malware infection was pretty severe. Icons were hidden, Programs were missing from All Programs. Task manager was hidden, etc, but after several scans with multiple anti-malware programs and Forefront and Microsoft Security Essentials, I finally got the hard drive to come up clean on the scans. I had removed the hard drive and connected it to a clean PC with an adapter. The Desktop icons and programs were still missing, so I started Googling. I ran Unhide, and ComboFix, ignoring the warnings not to use it unsupervised (bad idea). Unhide brought back the icons. I ran combofix, thinking that the infection was still infected.

The computer seemed fine after that, until I tried to update MalwareBytes. I had installed Microsoft Security Essentials, to replace McAfee. That was updating fine. I donít know if the network connection problem with the other programs means that the computer is still infected, or if maybe there is a simple solution. I did also try turning off the firewall, but that didnít make a difference. Rebuilding the computer is an option, but I figured since I have gotten this far, I should keep trying to fix the problem.

I hope someone can help, or if you think that rebuilding the computer is the way to go, thatís not a problem. I have experience rebuilding PCs, and I have the CDís.

Thank you!

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.

  • Upon completing the above steps and posting a reply, another staff member will review your topic and do their best to resolve your issues.

Thank you for your patience, and again sorry for the delay.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

You have stated that you no longer need help with this issue, therefore I am closing this topic. If that is not the case and you need or wish to continue with this topic, please send any Moderator a Personal Message (PM) that you would like this topic re-opened.
