Fixlist.txt

[Nbn]

I've attached all the files. Right now I'm wondering if there's a way to quickly remove all the "how_remove" files that the cryptowall ransomware added, and if there's any way to recover the files that were encrypted and are currently .ccc files.

cureit.txt

JRT.txt

AdwCleanerC2.txt

Fixlog.txt

[kevinf80]

Unless you have backups on a disconnected external hard drive the chances of recovery are probably nil. Have a read at the following link regarding information on Ransomware infections....

 

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

 

What is the current status, any remaining issues or concerns..

[Nbn]

I believe that everything is fine now, is there any harm in removing the "how_recover+pij" .htm/txt files that the ranssomeware left behind, it's in every folder on the computer. Also, do you recommend reinstalling programs as the ransomware may have encryped some files under Program Files.

[kevinf80]

Yes remove the files you quote, maby worthwhile saving them to a memory stick or other media. It is possible a fix maybe found later. Personally i`d put this down to experience and go for a fresh install of windows, your choice on that...

 

If you intend to keep the system as is, yes re-install any programs as you see fit... if no other issues we will need to clean up as follows....

 

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

Or use the following if first link is down:

"Delfix link mirror"

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…

One more question, I upgraded to a Windows 10. I was wondering if using the " Reset this PC" option in Windows 10 would remove any malware possibly remaining. 

[kevinf80]

When did you upgrade to Windows 10, the system we worked on was Windows 8.1 (X64)

[Nbn]

When did you upgrade to Windows 10, the system we worked on was Windows 8.1 (X64)

Just an hour ago, I was wondering if I should do a reset in case.

[kevinf80]

Was this an upgrade (retaining files, folders, programs etc) or a full clean install?

[Nbn]

It was an upgrade, that's why I was wondering if the reset option would be a good thing to. http://windows.microsoft.com/en-ca/windows-10/windows-10-recovery-options

[kevinf80]

The ransomware infection was removed from Windows 8.1, so we have a clean system. You then upgrade to Windows 10, why do you want to reset, what has happened since the upgrade, are there issues/problems?

[Nbn]

No additional problems, but you recommended a fresh install of windows.

[kevinf80]

I said that a clean install would be my preference, i would not have gone for an upgrade if there was the possibility of carrying an infection or remnants of the infection over... Look its past 1 am local time for me, i`ll have to catch up later, sleepy time for me...

 

As far as I was aware your system was clean when I posted instructions for the clean up with Delfix, if you suspect there are still issues i`d recommend a reformat and a clean install...
