Try checking the start up applications. If that item is listed there then it would be trying to start when the computer does and either it has parts still on the computer, or the uninstall didn't uninstall everything.
You would first need to make it not set to start up when Windows does, restart the computer and then try locating and uninstalling it again.
You need to make the above change in "MSConfig" (no quotes) and on the "startup" tab. Do not uncheck anything else in there unless you are completely certain it isn't needed. Otherwise you can wind up with loads of problems.
