System Cleanup Guide

  1. Sistemi ağdan DERHAL ayırın — diğer cihazlara yayılmayı durdurun
  2. Do not pay the ransom — there is no guarantee your files will be restored
  3. Quarantine the affected drives
  4. Kullanılan fidye yazılımı ailesini belirleyin (nomoreransom.org)
  5. Try available decryptor tools (the NoMoreRansom project)
  6. Report the incident to the authorities (cybercrime unit)
  7. Temiz bir yedekten kurtarın; yedeğiniz yoksa sürücüyü saklayın
