GLOBAL var for admincp?

[Antivirus]

Is there some sort of global variable which defines whether or not you are in the AdminCP?

What I am trying to do is following condition within hook: fetch_userinfo

if (!$within_admincp)
{
// do code here...
}

Perhaps try one of the constants that is defined at the start of the admincp global.php file:

// identify where we are
define('VB_AREA', 'AdminCP');
define('IN_CONTROL_PANEL', true);
