Removal Instructions

Follow these steps to completely remove the threat from your system

  1. 1
    Get Gridinsoft Anti-Malware — it's a quick 2 MB download that won't slow down your PC.
  2. 2
    Run the installer gsam-en-install.exe. The setup takes about 2 minutes and doesn't require a restart.
  3. 3
    The app launches right after installation. You'll see the main dashboard with the scan button front and center.
  4. 4
    Hit "Standard Scan" — this checks all the spots where malware typically hides: temp folders, browser data, startup programs, and system directories.
  5. 5
    Once the scan finds this threat, click "Clean Now". The removal usually happens instantly, though some stubborn infections may need a reboot.
  6. 6
    If you see a restart prompt, go ahead and reboot. This clears any malware that was running in memory and ensures your system starts fresh.
Important: Before You Start
Quick tip: unplug from the internet before scanning. Some malware phones home for instructions or downloads extra payloads when it senses trouble. If the infection is severe, boot into Safe Mode first — it limits what can run and makes cleanup easier.
