Hi Juank
this needs to go in the linux section where linux experts will see it

this is common linux/mac section :).
the updates are taken from port 80, but the target ip varies (just do dig files.avast.com). thus, at least, there must be the possibility to open tcp connection to port 80 to these machines. avast’s update uses the same mechanism as any http-get app (the update script might use internally wget too).
