Comodo says there are two systems running

Hi, I am a newbie and this is my first post. After downloading and activating Comodo I noticed that Comodo tells me there are two systems running and there are other programs running all the time -avgemc.exe and svhost.exe and my SDServices.exe and iexplore.exe. The AVG is at as is the iexplore. The SD is at the SVHost at and the two systems are both and at ports 137 & 138 respectively. Is this activity normal?
