I already have avast free installed on two machines. The promo for the upgraded version says it is free for up to 3 machines. If I upgrade to avast! Internet Security on one computer will the upgrade automatically take effect on the other one?
you must insert the avast! AIS license key in all the avast! versions you want to upgrade (and i think a standard AIS license is valid for 3 machines)

I assume that is the Internet Security Lic. file? yes?
