Sistem Temizleme Rehberi

  1. Sistemi ağdan ayırın — ethernet çıkarın, Wi-Fi devre dışı bırakın
  2. Görev Yöneticisi'nden şüpheli process'leri sonlandırın
  3. Malwarebytes veya Kaspersky ile tam sistem taraması yapın
  4. HKCU\Software\Microsoft\Windows\CurrentVersion\Run kayıtlarını kontrol edin
  5. Yeni oluşturulan görevleri Task Scheduler'dan inceleyin
  6. Tüm hesap şifrelerinizi güvenli bir cihazdan değiştirin
  7. Gerekirse Windows'u yeniden yükleyin ve verilerinizi temiz bir yedeğe geri alın
