IGFX virus

Hi,
I am very upset with the igfx virus, it started with igfxpers.exe, I have deleted it with the help of unlocker and removing its entry from startup, anslo creating “igfxpers.exe” folder, in system folder so that it do not recreate itself, but nw it creates igfxbs32.exe, igfxps32.exe and so on in every 2-3 days after removal. What it does is choke network, you cannot access internet, local shared folder unless you remove this. I have upgraded avast free editon to 6, updated it, scanned it boot time but it cannot remove the virus. Can anyone help??? And the surprising fact is that avast does not recognize it as virus??? So please tell me a way to get rid of the virus.
