Re: Email dumps
Well, it's not so much that they need to remove the malware.
Wikileaks likely has all kinds of viewers/readers, as they're mentioned in the general (non-IT) press reasonably often.
Not all of those users will have the depth/understanding needed to realise "hey, some of these files might not be safe...".
So, as others here have mentioned adding prominent warnings about malware being in some of the downloads sounds like a good idea. It would help clue in the people that don't realise.
