Hi,

First post - apologies if I get the process wrong or if this is too vague.

I'm almost certain there's a virus on my computer - which is 5 years old, running XP SP 3, normally using Spybot as the main AV software, and mainly using Chrome or Firefox as a browser (never IE, very very occasionally Safari). Having done a quick search online it seems to be some sort of version of Conficker, but I don't know any more than that.

I'm based in Africa at the moment, and when I took the computer to an internet cafe the guy took the computer and plugged in an ethernet cable before I could ask whether it was wireless or not. The computer basically froze up and closed Explorer at that point (when the cable was plugged in - not opening dodgy-looking emails etc), before bits of Explorer started reappearing; five minutes into this process the computer froze entirely, so I switched it off. Since then:

- I can't view hidden files on my computer, and there are 2 hidden files that weren't there before in My Documents (as well as in one or two MD subfolders)
- Windows Automatic Updates turns itself off at start-up
- I can't connect to the AU website, regardless of what browser I use
- My Clamwin AV software won't update (not sure whether that's virus-related though)
- Spybot's found a couple of Trojans and registry changes
- Scanning any USB sticks finds a "runonce.exe" file (which Rkill finds too) and one other worm, which it then cleans

The bigger issue is how to fix it. I've downloaded Combofix and tried to use it - a friend of mine was taking me through some of the steps - but it wouldn't run (i.e. it freezes, without fail, at either the "creating log report" or "scanning system" stage). Other things haven't run properly either - most notably the DDS scanner. The GMER log is attached.

I'm in Africa currently, so I don't connect every day, and my connection is pretty slow, if that affects how I can get any help.

Thanks,
Adam

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

Please take note:

  • If you have since resolved the original problem you were having, we would appreciate you letting us know.
  • If you are unable to create a log because your computer cannot start up successfully 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.
  • Please tell us if you have your original Windows CD/DVD available.
  • If you are unable to perform the steps we have recommended please try one more time and if unsuccessful alert us of such and we will design an alternate means of obtaining the necessary information.
  • If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • Upon completing the steps below another staff member will review your topic an do their best to resolve your issues.
  • If you have already posted a DDS log, please do so again, as your situation may have changed.
  • Use the 'Add Reply' and add the new log to this thread.

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:

How to create a GMER log


Thanks and again sorry for the delay.


Regards,
Georgi :hello:
