I have been infected with Runouce.B worm and have been able to remove for the last week. These are the steps I have followed.

1). The virus fills my drive up with readme.eml files on the C: drive, NAS, and thumbdrive.

2). I have removed all of the .eml files, clear the %TEMP% drive.

3). Removed any references to runouce.exe in the registry.

4). Removed the runouce.exe in the \windows\system32 directory.

5). Empty the prefetch directory.

6). Rebooted, and the file reappears in the registry run key.

I have run every worm removal tool, anti rootkit tool, and anti-virus tool I can get my hands on with no sucess. I have also tried Malawarebytes, and Super Anti-Spyware with no sucess in both safe mode and full sytem run state. I have researched the worm and found this is of little help because once the worm is started, it intercepts and replaces the running processes of malware/antiv virus tools.

I finally gave up and re-installed XP, but was immediately re-infected when I activated my Lacie NAS drive. This worm is killing me because once it starts I cannot connect to the internet, install Any other software because I get a system error telling me that the exe is damaged. I also cannot un-install sofware, which leads me to believe it breaks Windows Installer. I also cannot run Firefox or Chrome. I can get IE to run if I release and renew my DHCP IP address with ipconfig.

I have attached my log files as directed in http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/. At this point I' am at a loss at what to try next. I know that you need to see the worm running in the log files, but the only way for me to get online is to kill it's process, release and renew my IP address to allow me to run IE to post this help request. Also, I have attached 2 GMER logs because one run has data, but later runs log files are empty.

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.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

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 and take the steps necessary with you to get your machine back in working order clean and free of malware.

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.


Thanks and again sorry for the delay.

We need to see some information about what is happening in your machine. Please perform the following scan:
  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explaination 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



Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.


  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.
regards,
schrauber

Thanks for the reply. I made an attachment as a zip file. If this is not sufficent, p0lease let me know. The worm has affected me so much that I' m limited as to what I can do and not do. Creating zip files with Power Achriver, 7zip, and Winzip happens to be some of the programs affected. Please excuse the late response but I have been tied up with work.

TIA,
mhmallory

Microsoft Essentials indentified the worm as Win32/Chir.B@mm. I google'd and found http://threatinfo.trendmicro.com/vinfo/vir...2EB&VSect=T. This has ripped through my 2TB NAS, and infected the drive. Is it possibe to recover the infected files?

TIA,
mhmallory

Hello, mhmallory
Welcome to the Bleeping Computer Forums. My name is Thomas (Tom is fine), and I will be helping you fixing your problems.

If you do not make a reply in 5 days, we will have to close your topic.

You may want to keep the link to this topic in your favourites. Alternatively, you can click the button at the top bar of this topic and Track this Topic. The topics you are tracking can be found here.

Please take note of some guidelines for this fix:
  • Refrain from making any changes to your computer including installing/uninstall programs, deleting files, modifying the registry, and running scanners or tools. Doing so could cause changes to the directions I have to give you and prolong the time required. Further more, you should not be taking any advice relating to this computer from any other source throughout the course of this fix.
  • If you do not understand any step(s) provided, please do not hesitate to ask before continuing. I would much rather clarify instructions or explain them differently than have something important broken.
  • Even if things appear to be better, it might not mean we are finished. Please continue to follow my instructions and reply back until I give you the "all clean". We do not want to clean you part-way, only to have the system re-infect itself.
  • Please reply using the button in the lower right hand corner of your screen. Do not start a new topic. The logs that you post should be pasted directly into the reply. Only attach them if requested or if they do not fit into the post.
  • Old topics are closed after 3 days with no reply, and working topics are closed after 5 days. If for any reason you cannot complete instructions within that time, that's fine, just post back here so that we know you're still here.
  • Please set your system to show all files.
    Click Start, open My Computer, select the Tools menu and click Folder Options.
    Select the View Tab. Under the Hidden files and folders heading, select Show hidden files and folders.
    Uncheck: Hide file extensions for known file types
    Uncheck the Hide protected operating system files (recommended) option.
    Click Yes to confirm.




Please go here and have a look how you can disable your security software.

Download Combofix from any of the links below but rename it to before saving it to your desktop.

Link 1
Link 2



--------------------------------------------------------------------

Double click on the renamed Combofix.exe & follow the prompts.
    When finished, it will produce a report for you.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.



Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:



Click on Yes, to continue scanning for malware.

When finished, it will produce a log for you. Please include the C:\ComboFix.txt in your next reply.

This tool is not a toy and not for everyday use.
ComboFix SHOULD NOT be used unless requested by a forum helper
