Viruses that Norton is detecting: Backdoor.Ranky, Trojan.SpamThru, Trojan.Vundo?

Could someone help me? I have Norton antivirus that is detecting Backdoor.Ranky, Trojan.SpamThru, and Trojan.Vundo. I have installed AVS, FixVundo, Spybot, and Super AntiSpyware. They aren鈥檛 detecting anything except Norton and I鈥檝e tried Norton鈥檚 recommendations on how to remove them but they don鈥檛 work. It won鈥檛 fix it by itself it just is telling me to review their recommendations on how to remove it. Could you please help me? And give me a step by step way of removing these? I have Microsoft xp.

Try running Norton's recommendations in Safe Mode. Safe Mode often prevents malware from protecting itself.

Also, turn off System Restore to evict any copies of bad stuff that might be lurking there.

To get into Safe Mode:

1.Log out and reboot your machine.

2.When the machine starts the reboot sequence, press the F8 key repeatedly.

3.Select Safe Mode from the resulting menu.

4.When the login screen comes up, log in as Administrator. By default, Administrator has no password.

5.The machine will continue booting, but the Windows desktop will look different. You won't be able to see the Internet, for instance.

6.When you're finished, log out and reboot back into normal mode.

Note that even if the anti-malware procedure gets rid of the malware, it may not reverse the effects.
