Troj/Banker-ELO is a Trojan which attempts to steal login information related to Brazilian internet banks.
Troj/Banker-ELO copies itself to "<Documents and Settings>\All Users\Start Menu\Programs\Startup\Windows32.exe" in order to run itself on restart.
Troj/Banker-ELO also creates the following registry entry:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Windows32
C:\Arquivos de programas\Windows32.exe
The Trojan may create <Windows>\winload.inf which is an innocuous file and may be simply deleted.
