Removal Instructions

Follow these steps to completely remove the threat from your system

1
Get Gridinsoft Anti-Malware — it's a quick 2 MB download that won't slow down your PC.
2
Run the installer gsam-en-install.exe. The setup takes about 2 minutes and doesn't require a restart.
3
The app launches right after installation. You'll see the main dashboard with the scan button front and center.
4
Hit "Standard Scan" — this checks all the spots where malware typically hides: temp folders, browser data, startup programs, and system directories.
5
Once the scan finds this threat, click "Clean Now". The removal usually happens instantly, though some stubborn infections may need a reboot.
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.
