Good start up manager, for free?

When I start up, I keep getting a couple of AOL instant messenger dialog windows. I delete AOL instant messenger from start up but it returns every time I start up. I also had this problem something called P2P. I uninstalled it, but I might let my teenage granddaughter keep it installed if I can keep it off of start up.

Is there a simple, good, and free start up manager that would do the job for me? I see that there are a lot of start up managers but I have no idea how they compare.

I can't tell if start up cop has a free version or not. Also when I have tried to get to a place to download it, I keep getting, not a download window, but a window for subscribing to the magazine, PC something or other. I opted out of Goolge pop up stopper but that didn't help. If I should consider start up cop, how can I get to a download window?

Thanks, grandpaw7
