I run WireShark throughout the night and was wondering, what is the TCP, HTTP, and HTTP/XML data coming in from downloads.comodo.com during the night and early morning? I am using the free Comodo Firewall only. Thanks.

Probably CIS checking for programs or av updates.

I’ve always turned off updates and told Comodo to block itself. I’ve always wondered if it actually fully blocked itself or not. Never bothered to check though.
