Entourage 2004 Ghost Process??

Hello!
Just something strange I've noticed. I use iStat pro in my widgets, and I've noticed that every one in a while (quite regularly actually) I see a process named mdworker with the Entourage logo by the process. The issue is that I got rid of Entourage, and all of the Microsoft Office 2004 applications quite a while ago(roughly about 2 weeks ago). I've since used Spotlight to view and get rid of anything with the name Microsoft on my iMac, and it still shows up! It's not using a ton of resources, but I have to admit it's driving me crazy!

Yes I admit I'm being a bit picky, and perhaps a "little" obsessive, but can someone help me out, or let me know why I'm seeing this?

Any help or advice would be appreciated.
