Is there a website or free downloadable program that allows a user to identify and remove multiple types of malware from an ISO file?

Can malware infest an image file? I mean, beside naming an executable on Windows NudeJenniferLopez.jpg.exe and praying someoe is dumb enough to click it, does any image file format have enough executable or interperable parts to carry malware? –  Bruce Ediger Nov 9 '12 at 3:44
    
It would not be executable in itself directly, but say you're part of a botnet, it could issue updates through fully functioning bitmap (.bmp) pictures for example. However; as far as I know at least, the non-malware part must be stripped off. Proof of concept here: klevjers.com/dev/Bitmapper/Bitmapper.java –  Henning Klevjer Nov 9 '12 at 7:10
    
The image could exploit a vulnerability in a popular image viewer or codec, like the old ANI vulnerability in Windows. –  Polynomial Nov 9 '12 at 10:28

it could issue updates through fully functioning bitmap

So you're talking about stripping out steganography rather than neutralizing malware - in which case you'd get some mileage out of converting the file format (then possibly converting it back again). However it is technically possible to embed the content in such a way that it is still recoverable (IIRC the hidden WoW user id is extractable from a photo of the screen in addition to a direct image grab) e.g. if the image is of a barcode, then converting the format is not likely to disrupt the value embedded in the bar code.
