Troj/Bancos-BCV is a Trojan for the Windows platform.
When Troj/Bancos-BCV is installed it creates the file <System>\ntos.exe, which is also detected as Troj/Bancos-BCV.
Troj/Bancos-BCV also creates audio.dll and video.dll under the <System>\wsnpoem folder. These two files can be safely removed.
The following registry entry is changed to run ntos.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Userinit
<System>\userinit.exe,<System>\ntos.exe,
