There are three programs (all PowerPC) that are always running on my MacBook. Below is a pic of the ones I'm talking about. The top two I think are related to Norton Antivirus I used to have installed on my computer. I have since uninstalled them. I don't know why they are still there. The last one I believe must be related to Office, but I'm not too sure. Basically, how do I remove these (if they shouldn't be there)?
