fakegina.dll is installed with Fakegina Trojan (also known as ginastub Trojan) that intercepts the communication between Winlogon and the normal GINA (Windows NT authentication layer), and while doing this it captures all successful logins (domain, username, password) and writes them to a text file. If you find this process (file) on your computer, you should delete it and scan your computer with Spyware Doctor to ensure your privacy and sytem security.
