Ransomware manual removal milestones (optional and might not be effective):

  1. Restart your system into "Safe Mode with Command Prompt". While the PC is booting press the "F8 key" continuously, which should present the "Windows Advanced Options Menu" as presented in the image below. Apply the arrow keys in order to move to "Safe Mode with Command Prompt" and hit Enter key of your keyboard. Login as the same user you were previously logged in under the normal Windows mode.
  2. Once Windows boots successfully, the Windows command prompt would appear as described at the screenshot below. At the command prompt, type-in the word "explorer", and press Enter. Windows Explorer should open. Please do not yet close it. You can minimize it for a while.
  3. Afterwards open the Registry editor by applying the same Windows command prompt. Type-in the word "regedit" and hit Enter button of your keyboard. The Registry Editor should open.
  4. Find the following registry entry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\ In the right-side panel select the registry entry named Shell. Right click on this registry key and select "Modify" option. Its default value should be "Explorer.exe". However, ransomware did its job, and so after you click "Modify" you would see totally different value of this registry entry.
  5. Copy the location of the modified value of the above-mentioned registry entry to the piece of paper or memorize its location. It shows where exactly the main executable of ransomware is located.
  6. Modify the value of the registry entry back to "explorer.exe" and save the settings of the Registry Editor.
  7. Go to the location indicated in the value of modified registry entry. Remove the malicous file. Use the file location you copied into the piece of paper or otherwise noted in step in previous step. In our case, ransomware's virus file was located and running from the Desktop. There was a file called "contacts.exe", but it may have different (random) name.
  8. Get back to "Normal Mode". In order to reboot your PC, when at the command prompt, type-in the following phrase "shutdown /r /t 0" (without the quotation marks) and hit Enter button.
  9. The virus should be gone. However, in order to clean your PC from other possible virus threats and malware remnants, make sure to download and run GridinSoft Trojan Killer downloadable through the button below.
