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