What I don't get...

I installed Bearshare about two months ago and cannot remeber any mention of installing three other programs on my system during the install process ??

Do these programs sit in memory waiting for web browser activity?

I use my internet connection for more than surfing and file sharing and I need ever nano of performance I get when Im hooked upto the on-line gaming server's!

Do these programs run even if I don't use my web browser or p2p sharing, but I still have my connection active ?

Now Im really confused.
