spyblast

I have a big problem, I keep getting “Spyblast”,”People On Page” and some memory tester and can’t get rid of them no matter what I do. Every time I start IE 6.02 w/xpsp2,which is what I run, these keep coming up.You can uninstall spyblast but not POP or the memory counter and I can’t find them anywhere on my PC or don’t know where to look, can someone help me? This is driving me nuts!
Thanks,
Dave
