I don't have a winxp system in front of me at the moment, but you can try msconfig and seeing if there are any entries in your startup that are trying to run this (if there are, remove them).
If you don't have msconfig (or don't like to use it) I have found this alternative that will also allow you to view what is in your startup settings

also don't forget to try a free online virus scan just to make sure your system is clean
