Hello!

 

My computer has been infected by the Cryptowall virus.  I read several websites online and they state that all my data has been lost unless I have a viable backup available.  Of course I don't, but at the very least I need some help getting rid of the Cryptowall virus.

 

Can you please help?

 

Thanks!

Hello!

 

Thank you for your help!

 

I have attached a few files for you to review...but I've had some issues:

 

1.  MalwareBytes produced a blank log, although it found four issues.  I created a txt file listing the four files that were quarantined.

 

2.  I tried running RogueKiller multiples times and it keeps crashing!  Don't know what to do there.

 

3.  I have a copy of CryptoPrevent that I had running.  I have since turned that protection off (it prevented anything new, i.e. RogueKiller, etc.  from running)

 

Thank you again...I look forward to your reply!

Sorry about that...   I turned off CryptoPrevent, and re-started.  Re-ran Malwarebytes with no infections noted.  Re-ran FRST and posted the new logs below.  Tried running RogueKiller and it crashed again.

 

Other things - I had a dllhost.exe infection (that was cleaned with the help of TwinHeadedEagle at MalwareTips.com) right before I discover my files had been encrypted by CryptoWall...are the two issues related?

 

Thank you again for your help!

Yes they are.

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

Download the attached fixlist.txt to the same folder as FRST.exe/FRST64.exe.
Run FRST.exe/FRST64.exe and click Fix only once and wait
The tool will create a log (Fixlog.txt) in the folder, please post it to your reply.

You can re-enable it and don't forget to check for update often!!!

 

 

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


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

Please uninstall this and any other Java listed in your Programs and Features:
Java 7 Update 71


Then: <-------Download and install the latest version (Java™ 8 Update 25) from Here. Uncheck the box to install the Ask toolbar!!!, McAfee Security Scan Plus or any other free "stuff".

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

Adobe Reader 10.1.8 Adobe Reader out of Date!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.
