I got the computer brand new, and it apparently has a Motorola SM56 modem inside which isn't functioning anymore (I assume, because of the red "X" in system info). Do you think it's important to remove it? And is it definitely safe to remove it?

I tried PeerGuardian2, and I still have the setup files. It didn't seem to be helping, only using up memory, so I deleted it. But I'll try it again. Thanks for your help.
