need help ridding myself of smitfraud-c

[dying of frustration]

hello, i have just recently found out that i am infected with smitfraud-c. I have tried to fix it with spybot, but when i re- scan the computer it shows up again. I also had zlobdownloader.vcd but it seems to have been removed. i currently have spybot 1.5, ad aware se personal, and avg 7.5

i could really use some help with permanently ridding myself of this infestation.

thanks.

well, i just found the zlob.downloader.vcd again... and this morning, not only did a whole bunch of black boxes come up labeled spybot, but i had to repeatedly choose to accept or deny a change to spybot deleting something. i accepte all changes just because ive no idea what it is. anyone know wat that's about?
