Trying to remove cryptowall virus


Recommended Posts

I am trying to run MWB on my sister's computer that is infected with cryptowall virus. I tried to follow the instructions but malwarebytes will not run. I tried to install a new malwarebytes but keep getting some errors. Please see the FST and addition texts below:

 

I am unable to copy and paste into this message - I can copy but paste or ctrlP will not work.

    =============================

    Run RogueKiller again and click Scan

    When the scan completes > click on the Registry tab

    Put a check next to all of these and uncheck the rest: (if found)

    [suspicious.Path] (X64) HKEY_USERS\S-1-5-21-2159040480-875883246-3228997932-1000\Software\Microsoft\Windows\CurrentVersion\Run | chardkey : C:\Users\Shaw\AppData\Local\Temp\tzutdctr.exe -> FOUND

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

    Download the attached fixlist.txt to the same folder as FRST.exe/FRST64.exe.

    The tool will create a log (Fixlog.txt) in the folder, please post it to your reply.

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

    Please download and run ComboFix.

    The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

    Please visit this webpage for download links, and instructions for running ComboFix

    http://www.bleepingcomputer.com/combofix/how-to-use-combofix

    http://www.bleepingcomputer.com/download/combofix/dl/12/ <---ComboFix direct download

    Please make sure you click download buttons that look similar to this, not "sponsored ad links":

    bleep-crop.jpg

    Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

    Information on disabling your malware programs can be found Here.

    Make sure you run ComboFix from your desktop.

    Give it at least 30-45 minutes to finish if needed.

    Please include the C:\ComboFix.txt in your next reply for further review.

    ---------->NOTE<----------

    If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

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

    If you're using Malwarebytes 2.0, please run a Threat Scan

    Click on settings > Detection and Protection > Non-Malware Protection > PUP (Potentially Unwanted Program) detections > Make sure it's set to Treat detections as malware

    Same for PUM (Potentially Unwanted Modifications)

    Make sure "Scan for Rootkits" is checked.

    Quarantine All that's found

Good,

Does that mean we are virus free?

Well the infections you had are considered backdoor trojans ,and this is the usual warning we give people:
 

You're infected with Rootkit.ZeroAccess, a BackDoor Trojan.

BACKDOOR WARNING

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

One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would advice you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
http://www.dslreports.com/faq/10451

When Should I Format, How Should I Reinstall
http://www.dslreports.com/faq/10063

I will try my best to clean this machine but I can't guarantee that it will be 100% secure afterwards.


If this computer was used for sensitive business I would keep a close eye on your accounts and change all your passwords.

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

Lets check you compuyter for any adware while you're here:

Please download AdwCleaner from HERE or HERE to your desktop.

  • Double click on AdwCleaner.exe to run the tool.
    Vista/Windows 7/8 users right-click and select Run As Administrator
  • Click on the Scan button.
  • AdwCleaner will begin...be patient as the scan may take some time to complete.
  • When it's done you'll see: Pending: Please uncheck elements you don't want removed.
  • Now click on the Report button...a logfile (AdwCleaner[R0].txt) will open in Notepad for review.
  • Look over the log especially under Files/Folders for any program you want to save.
  • If there's a program you may want to save, just uncheck it from AdwCleaner.
  • If you're not sure, post the log for review. (all items found are either adware/spyware/foistware)
  • If you're ready to clean it all up.....click the Clean button.
  • After rebooting, a logfile report (AdwCleaner[s0].txt) will open automatically.
  • Copy and paste the contents of that logfile in your next reply.
  • A copy of that logfile will also be saved in the C:\AdwCleaner folder.
  • Items that are deleted are moved to the Quarantine Folder: C:\AdwCleaner\Quarantine
  • To restore an item that has been deleted:
  • Go to Tools > Quarantine Manager > check what you want restored > now click on Restore.

Out dated programs on the system are vulnerable to malware.
Please update or uninstall them:


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

Adobe Reader 10.1.10 Adobe Reader out of Date! <---please check for an update if available or uninstall and download and install Foxit Reader which is less vulnerable to malware and much better than Adobe. Don't install any toolbars that may come with it (ASK Toolbar).

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

A little clean up to do....

Please Uninstall ComboFix: (if you used it)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /

cf2.jpg

Then hit enter. (it may look like CF is re-installing but it's not)
This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall or download and run the uninstaller)

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

bwebb7v.jpgDownload Delfix from here and save it to your desktop. (you may already have this)

  • Ensure Remove disinfection tools is checked.
  • Click the Run button.
  • Reboot

Any other programs or logs that are still remaining, you can manually delete. (right click.....Delete)
IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST folder, FRST-OlderVersion folder, MBAR folder, etc....AdwCleaner > just run the program and click uninstall.

Note:
If you used FRST and can't delete the quarantine folder:
Download the fixlist.txt to the same folder as FRST.exe.
Run FRST.exe and click Fix only once and wait
That will delete the quarantine folder created by FRST.
The rest you can manually delete.

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

Any questions...please post back.

Take a look at My Preventive Maintenance to avoid being infected again.
