Your quick notification of the user base after being made aware of the issue is greatly appreciated, thanks. Unfortunately, this kind of stuff does happen. If I might make one suggestion, it would be for NMM to throw up a warning if a mod's zip contains a DLL or other obvious executable. This way the user could be warned to double check the mod description information to verify that this is a mod that is supposed to contain executable content -- there typically aren't many of them, so this shouldn't be too great an annoyance.
