Re: [clamav-users] javascript ZIP virus not caught?

There is at least one earlier discussion concerning the lack of response to submitted javascript samples, perhaps a month ago (sorry don’t have time to track it down at the moment). As I outlined earlier, there haven’t been many .js signatures to date, and hardly any recent ones that were not c
