Vista-can an infection migrate from drive to drive ?

I have Vista Home Premium.

The issue I'm dealing with is that I have a Trojan that infected Vista, then infected my flash drive when I plugged it in.

On this flash drive are all my programs which I'd like to save so I don't want to have them erased when I format the drive to get the infection off it.

I have a boot CD from a disk imaging program which has a partition manager so I can format this drive in that environment. However, when I plug in my portable drive so I can move my programs onto it, can the infection from the flash drive migrate on to the portable drive? Mind you, I won't be on C: any longer - in fact, to be sure the infection from C: can't migrate I'll be formatting C: FIRST so the infection will be gone and C: itself will be GONE, therefore no way it can migrate from Windows on to my portable drive when it's plugged in.

So, my question is :

In the boot disk environment, with Windows gone and drive C: unallocated, can the infection on the flash drive infect my portable drive which I'll plug in at that point?

I've never heard of any infection that can infect in that environment. Am I wrong that I can't be infected through this medium?

Please let me know.

Thanks for everyone's help ahead of time.

Any time you do ANYTHING with an infected drive short of formatting it, you run a risk of spreading any infections that may be present.

If I'm understanding your question correctly, the risk is probably minimal, but then you also can't move programs like that either, so...

Thanks for your reply.

What do you mean I can't move programs like that?

I believe I didn't make myself clear. I have the installers saved on the infected flash drive & my disk image program boot CD has a version of Windows Explorer which can be used to open any drive, and when in any drive you can copy, paste etc any files from one drive to another. In fact, I just did this as a test & copied a .txt file from one drive to another one (just to be sure I could do it).

Maybe you thought I meant moving programs from C onto a portable drive? I don't know, but hopefully I've made myself more clear.

In any case, are you saying that with what I have in mind, there should be minimal risk of the infection going from the flash drive to the portable drive since Windows will be gone & I'll be moving/copying the files while using the boot CD? Just making sure I understand you.

installers saved on the infected flash drive

Even though you have a disc-image on a CD; the risk of reinfecting your new (formatted) drive is dramitically increased, as whatever installers you have on the flash drive will be reintroduced onto your clean drive.

Before you go to the trouble of reformatting all your drives (including the flash drive), please try the following steps (as laid out by Grif) from another post;profileBot#3290628 Although this was used for someone infected using Windows XP, these steps work with all O/S.
