Question about svchost.exe permission box

Hopefully I am posting in the right place.

I searched the forums and found this thread that seems to be along the lines of my problem.

https://forums.comodo.com/help_for_v3/servicesexe_svchostexe_system_are_trying_to_connect_to_the_internet-t19956.0.html

I was unsure why I would be about to receive a connection from another computer so I blocked it even though I know that svchost.exe is needed.

I followed the instructions in the thread I mentioned and changed the permission to outgoing only for svchost.exe. However, Comodo is still blocking it. I dont know if it is just blocking whatever is trying to come in or whether it is the whole thing.

I am using wireless internet. Could this have something to do with connection to another computer?

I am really confused and having a hard time finding my way around Comodo. Any help would be appreciated.

Thanks.
