[Christopher E.]

Thank you very much for your help.

Hello,



They call me TwinHeadedEagle around here, and I'll be working with you.



Before we start please read and note the following:

• At the top of your post, please click on the "Watch thread" button and make sure to check Watch this thread...and receive email notifications. This will send an email to you as soon as I reply to your topic, allowing me to solve your problem faster.
• Please do not install any new software during the cleaning process other than the tools I provide for you. This can hinder the cleaning process. Please do not perform System Restore or any other restore.
• Instructions I give to you are very simple and made for complete beginner to follow. That's why you need to read through my instructions carefully and completely before executing them.
• Please do not run any tools other than the ones I ask you to, when I ask you to. Some of these tools can be very dangerous if used improperly. Also, if you use a tool that I have not requested you use, it can cause false positives, thereby delaying the complete cleaning of your machine.
  
• All tools we use here are completely clean and do not contain any malware. If your antivirus detects them as malicious, please disable your antivirus and then continue.
• If during the process you run across anything that is not in my instructions, please stop and ask. If any tool is running too much time (few hours), please stop and inform me.
• I visit forum several times at day, making sure to respond to everyone's topic as fast as possible. But bear in mind that I have private life like everyone and I cannot be here 24/7. So please be patient with me. Also, some infections require less, and some more time to be removed completely, so bear this in mind and be patient.
• Please stay with me until the end of all steps and procedures and I declare your system clean. Just because there is a lack of symptoms does not indicate a clean machine. If you solved your problem yourself, set aside two minutes to let me know.
  
• Please attach all report using
  
  button below. Doing this, you make it easier for me to analyze and fix your problem.
  
• Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay for the repair.
• If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

We won't support any piracy.
That being told, if any evidence of illegal OS, software, cracks/keygens or any other will be revealed, any further assistance will be suspended. If you are aware that there is this kind of stuff on your machine, remove it before proceeding!
The same applies to any use of P2P software: uTorrent, BitTorrent, Vuze, Kazaa, Ares... We don't provide any help for P2P, except for their removal. All P2P software has to be uninstalled or at least fully disabled before proceeding!

Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.

Running it on another one may cause damage and render the system unstable.

​

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

• Right-click on
  
  icon and select
  
  Run as Administrator to start the tool.
  (XP users click run after receipt of Windows Security Warning - Open File).
• Press the Fix button just once and wait.
• If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
• When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.

 

[Christopher E.]

Thank you for the quick response. I still don't have internet acces.

 

[TwinHeadedEagle]

Yes, malware is blocking its removal.

Scan with ComboFix

This is a very powerful tool that should be used only if advised by Malware Analyst.
Do not run ComboFix on your own!

Referring to this instruction, please download ComboFix by sUBs and save it to your desktop.
Temporary disable your AntiVirus and AntiSpyware protection - instructions here.

• Right-click on
  
  icon and select
  
  Run as Administrator to start the tool.
• Accept the disclaimer and agree if prompted to install Recovery Console.
• Do not take any actions while ComboFix goes through your System - it may cause it to stall!
• This scan may take some time!
• When finished - it will display a logfile (located also on your main drive, usually C:\ComboFix.txt).

Include that log in your next reply.

If you'll encounter any issues with internet connection after running ComboFix, please visit this link.

If an error about operation on the key marked for deletion will appear after running the tool, please reboot your machine.

Unfortunately some of the words in the attached file are in German. I do hope this is not a problem.

Fix with ComboFix

Let's prepare a Script for ComboFix to mark some things for being deleted.

• Press the
  
  + R on your keyboard at the same time.
• A Run window should appear in the lower left corner. Type in notepad.exe and press Enter.
• In the shown window paste in the following script:
  

  Driver::
  ColorMedia
  cmwf
  
  File::
  c:\windows\system32\Drivers\cmwf.sys

• Go to File menu and select Save as.
• Make sure that the Save as type option is set to Text files (*.txt) and the place to save will be your desktop.
• Name the file CFScript and select Save.

Your CFScript.txt file should appear on your desktop.

Temporary disable your AntiVirus and AntiSpyware protection - instructions here.

• Now drag your CFScript file and drop it onto the
  
  icon.
• This will start ComboFix. Let it run uninterrupted!
• A reboot may be needed during this run. Allow it.
• When finished, it shall produce a log for you at C:\ComboFix.txt and display it.

Please include that log in your next reply.

If you'll encounter any issues with internet connection after running ComboFix, please visit this link.

If an error about operation on the key marked for deletion will appear after running the tool, please reboot your machine.

Do not forget to turn on your previously switched-off protection software!

Very good. Now, I want you to follow my first message and execute FRST fix again.

It seems that we'll need to work outside Windows to fix this problem.

Please download Farbar Recovery Scan Tool x64 and save it to a flash drive.

• Plug the flashdrive into the infected PC.
• Restart your computer and tap F8 to bring up the Advanced Menu, then click Repair your computer
• Follow the prompt to enter keyboard input method, and then the prompt to enter a password. If the machine does not have a password, simply click Enter.
• In the Choose Recovery Tool menu select Command Prompt.
• You will see a big black window with a blinking cursor (command prompt).
  
  
  
  
  
  Access the notepad and identify your USB drive
  
  In the Command Prompt please type in:
  

  notepad

  and press Enter.
• When the notepad opens, go to File menu.
• Select Open.
• Go to Computer and search there for your USB drive letter.
• Note down the letter and close the notepad.
  
  
  
  
  
  Scan with Farbar Recovery Scan Tool
  
  Once back in the command prompt window, please do the following:
• Type in e:\frst64.exe and press Enter.
  You need to replace e with the letter of your USB drive taken from notepad!
• FRST will start to run. Give him a minute or so to load itself.
• Click Yes to Disclaimer.
• In the main console, please click Scan and wait.
• When finished it will produce a logfile named FRST.txt in the root of your pendrive and display it. Close that logfile.
  
  Transfer it to your clean machine and include it in your next reply.

Download attached fixlist.txt and save it to your USB flashdrive as fixlist.txt

>> Boot into Recovery Environment


Start FRST in a similar manner to when you ran a scan earlier, but this time when it opens ....

• Press the Fix button once and wait.
• FRST will process fixlist.txt
• When finished, it will produce a log fixlog.txt on your USB flashdrive.

>> Exit out of Recovery Environment and post me the log please.



Then follow the step in my first message. Tell me if you have Internet Connection now.

 

[Christopher E.]

Internet seems to work now. I will do some tests after your confirmation and I will come back to you.

 

[Christopher E.]

Everything works so far. Hats off to you, dear TwinHeadedEagle. You are really an expert. And a philanthropist. Thank you ever so much. I went already to your donation site to make sure that your twinheads get some beer. Regards from the South of Germany (Stuttgart). Christopher

The Importance of Software Updating:
​

In order to stay protected it is very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.​

Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.

Adblock - to surf the web without annoying ads!

Post-cleanup procedures:​

Download DelFix by Xplode and save it to your desktop.

• Run the tool by right click on the
  
  icon and Run as administrator option.
• Make sure that these ones are checked:
  • Remove disinfection tools
  • Purge system restore
  • Reset system settings
• Push Run and wait until the tool completes his work.
• All tools we used should be gone. Tool will create an report for you (C:\DelFix.txt)

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.
