Reoccurring instances (9) of DropSpam in Windows 2000 Server

I am finding 9 instances of DropSpam when running Spy-Bot S&D each week. These instances coincide with a slow down of internet related services and IE 6 locking up. It seems that there may be a file resident that is reloading this spyware on boot. Two of the keys that SPyBot is finding are:
 HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ANSMTO.MassSender
 HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ANSMTO.MassSender1
