Close Notepad.

NOTE: It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

Run FRST64 and press the Fix button just once and wait.

If the tool needed a restart please make sure you let the system restart normally and let the tool complete its run after restart.

The tool will make a log on the Desktop (Fixlog.txt). Attach it to your reply.

Note: If the tool warns you about an outdated version please download and run the updated version.

Hello!!

Thanks for the reply and the direction on this issue. I have run the Decrypter about 8-10 times using different source files, each time it apears to find the same encryption keys but it does not crack all the files. When I run the decrypter on the remaining files it still seems to find the same keys. I have attached the most recent key and log file returned.

 

Should I just go ahead with the remaining steps or keep trying the decrypter until all are un-encrypted?

 

THANKS AGAIN FOR THE HELP.

Thank again for the Help!!

 

I went back and started the whole process again just to make sure that you get the most up to date information. As I was searching for samples to run through the decoder I noticed there are several files that seemed to have been decrypted but the encrypted file still exists in the same folder. Can I just dump the encrypted version or is this some crafty ploy by the virus to trick me into re-infecting the system?

Yes, you can delete the encrypted copies, if they were successfully decrypted.

Let's take a fresh look.

Run fresh scans with Emsisoft Emergency Kit (EEK) and FRST, attach the new EEK and FRST scans to your reply.

Be sure to let me know how things are running.

OK, I have not worked with cleaning a lot of Viruses lately (I'm an Old School Mac-Head) but these logs look promising to me.

 

question: are the encrypted files just locked, or are they carriers of the virus also? (asking because I have 4 of them left. 2 I need to find replacements for and kept 2 to trigger the decrypter to run)

 

Thank again, a thousand times!!

The encrypted files pose no threat to the system, they are just encrypted.

Which files are still encrypted?

It is entirely possible that the files were not encrypted properly, resulting in files that cannot be decrypted.

Otherwise, your logs look fine.

Happy Holidays to you as well.

Unless you are having problems, it is time to do the final steps.

Now to remove most of the tools that we have used in fixing your machine:

Download Delfix from here and save it to your desktop.

  • Ensure Remove disinfection tools is checked.
  • Also place a checkmark next to:
    • Create registry backup
    • Purge system restore
  • Click the Run button.
When the tool is finished, a log will open in notepad. I do not need the log. You can close Notepad.

Empty the Recycle Bin

Download to your Desktop:

- CCleaner Portable

  • UnZip CCleaner Portable to a folder on your Desktop named CCleaner
Run CCleaner
  • Open the CCleaner Folder on your Desktop and double-click CCleaner.exe (32-bit) or CCleaner64.exe (64-bit)
  • Click "Options" and choose "Advanced"
  • Uncheck "Only delete files in Windows Temp folders older than 24 hours"
  • Then go back to "Cleaner" and click the "RunCleaner" button.
  • Exit CCleaner.
You can delete and uninstall any programs I had you download, that you do not wish to keep on the system.

Run Windows Update and update your Windows Operating System.
