BEASTY is a virus that destroys your PC, but it doesn't corrupt your files or like that, its just an annoying virus.

• Safe mode (Recommended)
• Using CMD on boot
• Reinstalling Windows
• Deleting it from it's base (Startup)

To remove it from safe mode, you must shutdown your PC. Then, you need to shutdown it at boot until a "Automatic Repair" message appears. Wait until it finishes. Then, go to advanced settings. It should appear some options. Click on safe mode. Choose a mode, and then go ahead. On safe mode, use Win + R and write shell:startup. Then, delete the bat file. Don't forget to delete the hidden scripts.

Follow the steps above. But instead of selecting safe mode, use CMD. Then write notepad. Go to C:\Users(Your user)\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Start and delete the files.

This is the WORST way to remove it. You can lost data and, maybe the entire disk if you don't have a cloud (OneDrive, Drive, MEGA, etc.) You can get Windows 10 ISO from the Microsoft Official Page.

This is a REALLY HARD way, because due to loop, you couldn't make it. But you must use Win + R and write shell:startup. Then delete the files and restart.

I'm not responsible from any damage or data loss on the making of these steps. If you pressed a wrong button, then you are responsible of the damage or data loss.
