Using a repacked or cracked VPN client carries significant security and privacy risks that directly undermine the purpose of using a VPN.

If you have already downloaded a repack, do not wait for it to fail. Run a full offline antivirus scan (Windows Defender Offline or Kaspersky Rescue Disk). Change all your passwords using a clean device. Uninstall the repack manually by deleting the Program Files folder and cleaning the Registry.
