My Pc was originally infected with the ramnit.c virus some months ago with additional infections as outlined below. I have run several scans/malware removal tools including tdss killer, microsoft windows malicious software removal tool and malwarebytes. The misrosoft tool seemed to do a good job and removed alureon.a and ramnit.gen!a. Ramnit.d was partially removed and then seems to have been fully removed after the other scans. ramnit.c was actually not detected - I think an earlier scan using malwarebytes and other removal tools (run in a local computer shop) removed it. My PC is certainly running faster than it was and now runs at 3% instead of 100% on the CPU. The floppy drive has also stopped constantly switching on and off which it started to do after I got the infection. I ran an eset scan 3 times and as you will see from the attached logs the first log removed 5 infected files (not ramnit) but was 'unable to clean' 21 files infected with ramnit.a. I'm not sure if this is because these have been quaranteened by one of the other removal tools. CCleaner, which was detecting multiple files being opened and re-opened constantly when I had the infection, has stopped detecting that the same files are being opened over and over and is no longer finding anything 'unusual'. Please could you advise what the next step should be. Thanks.

Hello and welcome to Bleeping Computer!

I am HelpBot: an automated program designed to help the Bleeping Computer Staff better assist you! This message contains very important information, so please read through all of it before doing anything.

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.

To help Bleeping Computer better assist you please perform the following steps:

If you no longer need help, then all you needed to do was the previous instructions of telling me so. You can skip the rest of this post. If you do need help please continue with Step 2 below.

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

Posted Image If you still need help, I would like you to post a Reply to this topic (click the "Add Reply" button in the lower right hand of this page). In that reply, please include the following information:

  • 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.
  • Please tell us if you have your original Windows CD/DVD available.
  • 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:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!

Hello,

I'm afraid I have bad news. Win32/Ramnit.A is a file infector with IRCBot functionality which infects .exe, and .HTML/HTM files, and opens a back door that compromises your computer. Using this backdoor, a remote attacker can access and instruct the infected computer to download and execute more malicious files.
With this particular infection the safest solution and only sure way to remove it effectively is to reformat and reinstall the OS.

Why? The malware injects code in legitimate files similar to the Virut virus and in many cases the infected files (which could number in the thousands) cannot be disinfected properly by your anti-virus. When disinfection is attempted, the files often become corrupted and the system may become unstable or irreparable. The longer Ramnit.A remains on a computer, the more files it infects and corrupts so the degree of infection can vary.

Ramnit.A is not effectively disinfectable, so your best option is to perform a full reformat as there is no guarantee this infection can be completely removed. In most instances it may have caused so much damage to your system files that it cannot be completely cleaned or repaired. Further, your machine has likely been compromised by the backdoor Trojan and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if your anti-virus reports that the malware appears to have been removed.

I'm sorry I don't have better news for you.
