tatanga zeus banking trojan

Hi there,

A friend of mine, who is an accountant has had her internet banking shut down by the bank and informed that her computer has been hacked by the tatanga zeus banking trojan. Now because she is an accountant i dont really want to take the risk of thinking the virus has been removed when it might not be due to the fact she has various client details.

Has anyone dealt with removing this trojan before?

thanks
