Default Block All Inbound Windows Services (Public Networks) rejected TCP(6) traffic with community.norton.com

I dont understand what is rejected case meaning? rejected community.norton.com traffic?
every time go web there is new log list in my norton history, like:

Category: Firewall - Activities
Date & Time,Risk,Activity,Status,Recommended Action,Category
19/08/2016 22:21:36,Info," Rule \"Default Block All Inbound Windows Services (Public Networks)\" rejected  TCP(6)  traffic with community.norton.com (151.101.44.214  Port https(443) )",Detected,No Action Required,Firewall - Activities
    Firewall rule was matched:<br>    Rule Name: "Default Block All Inbound Windows Services (Public Networks)"<br>    Rule Action: rejected<br>    Rule Severity: normal<br>    <br>    Traffic Details:<br>    Protocol:  TCP(6) <br>    Direction: inbound<br>    Local Host: VINSENS-LAPTOP<br>    Local IP: 10.74.111.xxx<br>    Local Service:  Port (1293) <br>    Remote Host: community.norton.com<br>    Remote IP: 151.101.44.214<br>    Remote Service:  Port https(443) <br>    Remote MAC:  -- <br>    Adapter Index: 56<br>    <br>    Process Information:<br>    Process ID: 4<br>    Process Path: System<br> 

When I go to smart firewall there is some new block rules (block windows RPC, block media player extender, block remote assistance,... etc)
where is that come from? automatically generate?
what if I delete that rules? its safe?

Thanks all
