imadreamer2: I don't think I've read an answer for your particular question. If the partitions are just different drive letters running under the same operating system (like D, E etc., all on the same physical "C" HD), I would be concerned. If my understanding is correct, once the C drive is exploited, anything on the disk would have to suffer the same fate as C. (That still doesn't necessarily mean data couldn't be salvaged...)

If you have 2 bootable operating systems on one drive, that might be different/better. But I have also read this thing can place rootkit corruptions in Windows system files. So I guess no one really knows how bad this could get...
