I notice while watching Process Explorer that msnmsgr.exe is consuming a huge amount of CPU time. I use msn/verizon as my browser but never use the messenger service at all, and would just as soon it doesn't load at startup because it just wastes time. I don't know what the messenger service is doing at all, including monitoring my internet activity and so on. Is there a way I can safely disable this one process, so that if necessary I can reverse it; I need the msn browser function after all. I don't think I can block it through XP's Internet Options - it's not a site or an ActiveX or cookie. I did not see anything in Spybot that looked promising as a tool either. Thanks for your help.
