listening on ports

I’m looking at the View Active Connections… and i have some listening… is this bad? should i block these?

I used to be able to block certain addresses/ports with an older version with ease… but now when i do it its asking for an application…

do i just select svchost.exe as its application?

Side Note:
man i hate that svchost… got like 7 of them running and taking up alot of memory and bandwidth… lol

LOLOL… you must be on XP. On Vista and Win 7 you will find even more instances of svchost running. I am on Win 7 and have 12 instances running…;D

Programs listening is nothing bad when you know the programs and that they are legit.
