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