Vundo spyware/virus

My system is infected with Vundo virus or spyware.

I tried all sorts of ways available on the net...used Symantecs FixVundo tool...bt it said Trojan.Vundo has not been found on your computer.

I've latest McAfee updated, it does detecs the infected file but unable to clean/quarantine/delete it.

I'm pissed of guys....how many times to re-install Windows????

Now which antivirus to trust???
How shall i remove Vundo.
