Coudn't find any help topic, neither any forum topic about it... I just found that the main Avast menu had some option called (sorry for the translation i have the french version):
"File -> Create Silent Install"
I just tried it out, thinking it was a way of installing Avast on my network computers in a remote way... is that right

? I"m not sure to do it the right way, could anyone tell me more about it ??
