Cryptowall 3.0


Recommended Posts

hi,

I should preface by saying that I am not very computer savy, so if at all possible, please have patience.

about a year and a half ago, I got cryptowall 3.0 on my computer. I believe I got it from plugging a friends camera into my computer, because I got the infection(?) immediately after that. At that time, I couldn't find much on cryptowall or how to remove it. The only thing I found, was an article saying to maually search for and remove certain files (I believe they were "help_decrypt" or something like that. I have done that and my computer no longer has those fun little pop-ups. So I figured it was gone. I ran malwarbytes numerous times since then. My computer seems to be running okish, but it is reeeeally slow as though something is still wrong with it. Its to the point that I don't even use the laptop anymore. I don't want to throw it away, which is my first instinct, because it belonged to a deceased family member. Could the slow computer be a result of cryptowall still being on the laptop? How can I find out what is wrong? What can I do? Is there anyway to save the files still encrypted? It would appear that the infection deleted all restore points so I was unable to restore to an earlier time. There are a lot of files that I would really like to restore on there as well as getting the laptop back in working order.

Thanks in advance.

I have done the AdwCleaner part.  Log attached.  I wasn't sure what you meant by, "Where * is the number relative to list of scans complete...".  I hope I did it correctly.  Please let me know if I haven't and I will do it over.  Moving on to the Farbar recovery scan tool part.

 

SIde note:  My computer is already running better.  Not slow to start anymore.  Thanks.

Thanks for the logs, continue as follows:

 

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into.
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Run FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Hi Kevin,

 

thanks for the quick reply.  I have downloaded the "fixlist.txt" file onto desktop, opened FRST and clicked fix.  It created the fixlog you mentioned which I will attach.  I got a popup (I will attach a screenshot), I clicked off of that popup and it immediately closed and closed my browser as well (which was on this forum), then 3 of my browser popped up with my default "homepage" open instead of this forum.  Not sure what happened.  The FRST program after I clicked "Fix" says "deleting temporary files on the top and the "fix" button now says "fixing".  Hope I am doing this correctly.  I will attach the fixlog and screenshot below while I wait for FRST to finish deleting temporary files.? 

 

Thanks Kevin

sorry for taking a while to reply, I wanted to give it a couple of days to see how my laptop does.  It does seem a little slow on start but sooo much better.  Is there any known way to retrieve the files that were encoded with the cryptowall?  I really would like to see if I could get those back.  My restore points were deleted when cryptowall showed up on my laptop, so that won't work.  I've seen some posts around about something called "shadow___" something like that.  Would that work?

 

Thanks for all the help Kevin.

You are referring to shadow volume copies, unfortunately the type of infection you had normally removes those backups, it is still worth checking. Bleeping Comptures have a tutorial with the information you require. Please read up at the following link:

 

http://www.bleepingcomputer.com/virus-removal/cryptowall-ransomware-information#shadow

 

Run the following to clean up tools used etc...

 

Download "Delfix by Xplode" and save it to your desktop.

Or use the following if first link is down:

"Delfix link mirror"

If your security program alerts to Delfix either, accept the alert or turn your security off.

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

Make Sure the following items are checked:



  •    
  • Remove disinfection tools
       
  • Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created.
       
  • Reset system settings



Now click on "Run" and wait patiently until the tool has completed.

The tool will create a log when it has completed. We don't need you to post this.

Any remnant files/logs from tools we have used can be deleted…
