Windows Defender Beta 2

Hello Isaac,

MSAScui.exe is the program that provides the UI, but is always running as a
user mode process, as I understand it. The Windows Defender service is
provided by
msmpeng.exe and runs as a system service--you can see it at a
command prompt by typing net start and looking at the end of the list, or
via other ways of looking at running services.

mpcmdrun.exe is a command-line executable which triggers and monitors
signature updates from the app (via help, about, for example--or when
specified in general options as happening before a scheduled scan--and which
does scanning. It lives in \program files\windows defender and you can run
it and get syntax info, which seems to confuse everyone who has looked at
it!

So--if a scan or sig update is in progress, you'd see mpcmdrun.exe.
Otherwise, both msmpeng.exe and msascui.exe should be listed.

The system tray icon for Windows Defender (Beta 2) will not be visible if no
action is needed. This is expected behavior.

icono al lado del reloj ni nada, solo si se actualiza. Se activa solo tipo
antivirus o para usarlo hay que hacerlo manualmente?
