Removing exploit:win32/cve-2011-0096

[schen60]

So I have both Malwarebytes and Microsoft Essentials. Now recently, Microsoft Essentials detected a virus called exploit:win32/cve-2011-0096. When it tried to remove it, it never worked. So I tried to remove it with Malwarebytes but it never detects it though. I've also tried Microsoft Security Scanner but it was only able to partially remove it. I want to remove this virus permanently so any help is greatly appreciated. 

 

I have a Fujitsu Tablet that runs Windows 7 64-bit.

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.

Hello Marius, 

 

Thank you for helping me. Here is what you requested, I wasn't sure if I was suppose to attach a file or just paste it on here. Unfortunately, I tried to paste it on here but it said my post was too long. So for now, I'm attaching my files. I hope that is all right.

Combofix

Combofix should only be run when adviced by a team member!

Link


Important - Save the file to your desktop!

• Deactivate any and all of your antivirus programs /spyware scanners - they can prevent CF from doing its work.
• Run Combofix.exe
  

When finished, Combofix creates a log file named C:\Combofix.txt. Please post its content in your next reply.

Note: When receiving an error message containing ""Illegal operation attempted on a registry key that has been marked for deletion" simply restart your computer to fix this.

[schen60]

Ok, here it is.

Combofix scripting

1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Download the attached CFScript.txt and save it to the location where Combofix is.





Refering to the picture above, drag CFScript into ComboFix.exe

When finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Recommendations: How to protect yourself

• System Updates
  Please ensure to have automatic updates activated in your control panel.
  For further information and a tutorial, see this Microsoft Support article.
• Protection
  What you need is one (not more) virus scanner with background protection. Additionally I recommend a special malware scanner to run on demand weekly.
  Personally I am using avast! Antivirus Free Edition and Malwarebytes Anti-Malware. They offer good protection for free.
  
  • To keep your browser free of advertising, you may install the Adblock Plus browser extension.
    It will filter unwanted advertising out of the website´s content.
  • To protect yourself from accidentally visiting malicious web sites, install the Web of Trust (WOT) browser extension.
    It will display a green (safe), yellow (unknown) or red (potentially dangerous) icon for a visited website within your browser.
    In addition, before accessing a dangerous classified web site, a warning screen is displayed.
    

  
  [*]Up to date Software
  Keep your Windows and your third party software up to date. The easiest way to get infected is an outdated windows, followed by: browser(s) (including add-ons and plug-ins), Adobe Flash Player and Adobe Reader, Java Runtime Environment, your antivirus program and so on. These links may help you to check:
  

  • Secunia Personal Software Inspector - checks if your software has updates available.
  • SecurityCheck (by screen317) - scans your computer for most vulnerable outdated software.
  • Mozilla: Check your plugins - The webpage will tell you if you have outdated plugins running in your Firefox browser.
    

  [*]Backup
  Hardware issues, malware, fire, lightning strike: There is a long list of different ways to loose all your data. Back up your files regularly. Use the windows internal backup function or a third party tool and save your data onto an external hard drive, cloud storage, optical media like CDs or DVDs or (if available) a professional network backup system. [*]Behaviour
  The commonest error when using a computer is "error 80" - what means that the error is located about 80cm in front of the monitor. This is a common joke between IT support technicians but it shows that all the safety mechanisms won´t help if you aren´t careful enough.
  

  • While surfing the internet, don´t click on anything you don´t know. In the worst case, it infects your system with malware.
  • Watch your step in social networks! Many cyber criminals use them to spread malware, mine personal pata (to be sold to advertising companies, for example) or simply do damage to other users. Even if a received hyperlink within a message seems to be coming from one of your friends, have a closer look. In addition, don´t click everything.
  • When installing software, have a look to each of the setup windows and uncheck any additional toolbars or free programs that may be offered additionally. Most of today´s setup procedures contain potentially unwanted programs so keep them off your system.
  • Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs.
    They are a security risk which can make your computer susceptible to a wide variety of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites.
