i received unwanted downloads after downloading Microsoft Office
 

Im a limewire user and after I successfully downloaded Microsoft Office 2000 and installed it, I found that there were an extra 1200 or so more files which I DID NOT choose to download in my shared folder, why the heck does this happen? So I went to "my computer" and checked out contents of my shared folder and erased all these unwanted downloads, but when i restarted the comp., the unwanted downloads came back. How do i stop this?Please help!
