Solved I have cryptowall virus, hopefully you can help

[Sue64]

I have been having trouble posting to the forum so am on another computer. If this works, I'll upload the logs in another post

That worked, so back on the infected PC now. Here are the logs

Hello,


You probably know that we cannot bring back your files back, they are unfortunately encrypted, without being able to decrypt again. We can clear the infection only.

Please read this FAQ --> http://www.bleepingcomputer.com/virus-removal/cryptowall-ransomware-information

 

[Sue64]

Hi, Thanks for your reply. Yes, I understand we will not be able to recover the files. I read the information you suggested, thanks

Run FRST again, check Addition.txt, press scan and attach both reports.

I tried to run the scan, but it started and then wouldn't complete. It froze when it got to "extra checks". It only produced 1 log, which I have attached

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.

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.

Sorry, I can't see where you have attached the fixlist.txt file

 

[TwinHeadedEagle]

Sorry, try now.

 

[Sue64]

Thanks, I have done those 2 scans, and I have attached the logs

I have run the scan, it didn't find anything. The log is attached.
I have noticed that I am no longer getting the cryptowall messages popping up, but have still got random "decrypt..." files on the computer.
I also noticed that I can't open the email progam (microsoft outlook) This is the error message "cannot open your default email folders. The file ... (location.pst)... is not a personal folders file" I'm not sure if this is a new problem or not as haven't tried to open it for awhile. Could this be connected to the crypotwall problem?

 

[TwinHeadedEagle]

There is new site launched to help people bring their files back.

[Sue64]

Sorry for the late reply, but had to work yesterday. I'll try those today and let you know how I get on. Great news that the PC is clean now, thanks

I tried the decrypcryptolocker site. I got a message about a certificate error, and then the file wouldn't upload. I tried it on my laptop, no error this time, so transferred a corrupted file to a memory stick and uploaded it successfully. I got an message saying that the file did not appear to be corrupted by cryptolocker. Could this be because I had crypotowall instead?

I looked at the link regarding the email problem. The error message it describes is different to the one I get when I try to open outlook, however I did try to repair the offline folder using scanost.exe. This wouldn't work, the message said it wasn't compatible with my version of outlook. I checked that it wasn't running in compatibility mode. The article refers to .ost file problems, my error message refers to a .pst file. Maybe they are the same thing?, I don't know.
