Spyware help?

Can anyone suggest good software to remove spyware from an XP? I believe its a trojan that has infected the computer because 4 new icons popped up that i didn't put on there. They are called things like spyware remover etc. Every few minutes a thing pops up. Like your computer is vulnerable to viruses as your computer has sensed virus activities. And a webpage pops up every few minutes also. I ran norton antivirus but it didn't find anything. Also i downloaded Spyware doctor. It found many cookies and one trojan downloader, which i fixed. But the virus trojan thing, spyware is still on there. Also the computer runs very slow. Can anyone help me! I will be forever thankfull. P.S Could the software preferably be free but if it will fix my computer i don't care if i have to pay for it.

Besides the two online scans suggested by JibbarJabbar, another good free online scan which removes what it finds is the Eset Online Scanner. It has the same scanning engine as the famous NOD32 antivirus.

I had the problem too and Spyware doctor did Sh(CENSORED!!!!!) to help. Neither did Norton. I had a terrbile lagg everytime i tried to do something.

Eventually, i got all my files on a flash drive and reinstalled windows, deleting everything else. After, the PC ran like new. I'm not saying you should do this, but i'm just saying you should use it as a last resort if everythign else fails.
