Win32 Vundo Removal

Every search I do for free removal software allows you to download their software, but then they try and charge for the removal part. Are there any absolutely free ones? And if not – how can I get rid of it before it drives me nuts???

I recently d/l the free version and ran the full scan and it found the Trojan Horse. I clicked on Heal, but it didn’t do anything. I clicked on Virus Vault and see the file listed in there, but how do I get it removed?
