Trojan.Zeroaccess and Trojan.Gen.2

Hi,

I am using windows 7 ultimate 64-bit and i got a virus called Trojan.Zeroaccess on my computer (yesterday it said it was Trojan.Zeroaccess.B). Power Eraser did not work and Symantec realizes that Trajan.Zeroaccess is there but can't do anything about it. It says 2 Trojan.Zeroaccess are 'Backup' and probably about 18 Trojan.Gen.2 are 'Quarentine'. Please help this computer was super expensive! Thanks.
