Norton Internet Security 2009 Questions, Help Needed Please!

Hello, recently I have been getting messages in my history such as:

 

"Unused port blocking has blocked connections. Inbound TPC Connection. Remote adress, local service is (my IP)."

 

"Rule 'default block UPnP Discovery' stealthed (my IP, port ssdp (1900) ). Inbound UDP Packet."

 

"Rule 'default block Microsoft windows 2000 SMB' blocked (My IP, Port (445) )."

 

"Rule 'default block LLMNR' stealthed (My IP, Port (5355) ). Inbound UDP Packet." 

 

And

 

"An instance of Google chrome is preparing to access the internet." 

 

Also, when i connect to my Linksys it says "protecting your connection to a newly detected network adapter "Dell wireless... (My IP)." And when i disconnect it says that it has dissapeared.

 

All of the messages that i listed keep popping up about every 10 seconds, on and off. When will they stop? :(  

 

All of the things said above are only listed as "info," not a low-risk. Does this mean that i have nothing to worry about? 


 

Please, i would really appreciate any assistance as to what is going on. I am nervous, am i being hacked? Could someone also explain what all the ports have to do with it.

 

Any help appreciated, thanks very much.
