I have a 32 bit Windows XP Home Edition PC.  On Wednesday 6/11/2014 at about 9:20 p.m., I was working on my PC when my antivirus software Microsoft Security Essentials (MSE) detected a malicious file.  MSE cleaned my PC and then prompted to delete the file which I did.  The name of the file was Exploit:Win32/ShellCode:A.


I subsequently scanned my PC with Malwarebytes.  The Malwarebytes scan found one malicious file which I deleted when prompted.  The log of the Malwarebytes scan is shown below:


Malwarebytes Anti-Malware

C:\Documents and Settings\Owner\Local Settings\temp\UpdateFlashPlayer_2ef15b2a.exe (Trojan.Inject) -> Quarantined and deleted successfully.


On Thursday 6/12/2014, I ran a Super Antispyware Free Edition scan which found no malicious files. I then ran an MSE quick scan which found the following two threats:

Virus:DOS/Ronvix.W boot:\\.\PHYSICALDRIVE\Partition0 (NTFS)

Virus:Win32/Ronvix.gen!B rootkit:Ronvix->Vbr::Ronvix


When prompted on whether I want to remove these threats, I answered yes, but MSE told me that in order to clean my computer completely I need to download and run Microsoft Offline Defender.  I followed the instructions to download the Microsoft Offline Defender software, but when I attempted to run it I was told that I do not have the necessary system requirements.  Apparently, Microsoft Offline Defender can no longer be run on PC's with XP operating systems.


In light of this problem, I need assistance on how to completely remove the malware on my PC.


Thank you.

Hi there,
my name is Marius and I will assist you with your malware related problems.

Before we move on, please read the following points carefully.

  • First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
  • Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
  • Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
  • Stay with me. I will give you some advice about prevention after the cleanup process. Absence of symptoms does not always mean the computer is clean.
  • My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.

HijackThis is not the preferred initial scanning tool in this forum. With today's malware, a more comprehensive set of logs is required to determine the presence of malware.
Scan with FRST in normal mode

Please download Farbar's Recovery Scan Tool to your desktop: FRST 32bit or FRST 64bit (If not sure: Start --> Computer (right click) --> properties)
  • Run FRST.
  • Don´t change one of the checkboxes and hit Scan.
  • Logfiles are created on your desktop.
  • Poste the FRST.txt and (after the first scan only!) the Addition.txt.

Scan with TDSS-Killer

Please read and follow these instructions carefully. We do not want it to fix anything yet (if found), we need to see a report first.

Download TDSSKiller.zip and extract to your desktop
  • Execute TDSSKiller.exe by doubleclicking on it.
  • Press Start Scan
  • If Malicious objects are found, do NOT select Copy to quarantine. Change the action to Skip, and save the log.
  • Once complete, a log will be produced at the root drive which is typically C:\ ,for example, C:\TDSSKiller.<version_date_time>log.txt

Please attach this file to your next reply.
