Svchost and System

Comodo Internet Security - CIS Firewall Help - CIS

I’m receiving a lot of connections from “System” in several ports like: 445, 139, 137 and different IP Adresses
Also from “Svchost”.
In rules I put Svchost like “outgoing only” and System “Block and log all incoming request…”

Here’s a screen: http://img404.imageshack.us/img404/8889/portsz.png

Every day I receive like 300 connections and Comodo blocks them.

Are those connections malicious? Should I keep blocked them?

Thanks for your answers!

No they are not malicious because they are coming from the same subnet as your IP address, windows automatically looks for network shares on the same subnet, but you should keep blocking them. However, if you do not want to see these reports flooding your log then you should block without logging enabled.
