Troj/Banker-HE is a password-stealing Trojan for the Windows platform. 
Troj/Banker-HE creates the file winllogon.exe in the Sys\ subfolder of the 
Windows folder, creating this subfolder if it didn't exist. This file is also 
detected as Troj/Banker-HE. 
Troj/Banker-HE monitors browser activity for visits to specific banking 
websites. On detecting such activity, the Trojan displays a fake login page and 
records keystrokes in an attempt to steal login details. Any information stolen 
in this manner is submitted to the author by email. 
Troj/Banker-HE downloads a file from a preconfigured URL and executes it. At 
the time of writing, this file is a self-extracting archive containing several 
images required for displaying the fake login pages, but no further executable 
code. 

This IDE file also includes detection for:
