Task Manager at Startup

In the last day or two Task Manager has been popping up in the System Tray at startup. It never used to. It also says personalized settings for Internet Explorer 5.5 in a box in the upper left corner. I have the program Startup Manager and can’t find it in there to disable it. I don’t know how to get rid of it. If it helps any I am running Windows 95. My newest download that could have caused this would be the brand new MSN Messenger (Version 4.5). Any help will be appreciated.
