Every time I update to a new IS version, the firewall in the new version begins blocking my home network, which the previous version allowed.
Every time I have to either livechat Kaspersky tech support to fix this, or figure it out myself.
This time tech support wasted my time going to general websites that didn't help, or asking me for all kinds of irrelevant info, even though I told them I knew it was the firewall.
So, this time, I had to spend my time to figure out (each version is different) and fix the problem. I'm not an IT person, and this is not okay.

WHEN YOU CHANGE VERSIONS, PLEASE MAKE SURE THE FIREWALL IS SET TO TRUST AND ALLOW THE SAME NETWORK(S) THAT THE OLD VERSION ALLOWED!!!!!!!

IT'S A GOOD PRODUCT, BUT THIS IS A FLAW AND A PAIN.

hello
due to the fact that the firewall logic is build from the ground up, settings aren't transfered from v7 for it, also the firewall will never set it to trusted, but between local and public, trusted is only available through manual setting via popup or network settings.
