My friend is going to be an OP on a chat network. He was wondering if there is a way to find out waht scripts/addons users have loaded in their mIRC, and this is to prevent users to have downloader, spam addons, and those annoying viruses that send message to any user which joins the channel.

My question is: Is it possible at all?
Can it be done with mIRC scripting?
If not, do you know of any software that is capable of such functuality?

Thanks
