Isn't it illegal for someone to add a backdoor trojan to a mirc script and make it avaible to the public. If so please link me to info on the subject..thanks a lot

remote access/entry to someones computer without their permission and knowledge is illegal.

thanks dan, do you know of a link i can use as per laws i can quote to this guy and his isp provider?
again thanks

It depends on what country the person is in, what country the server he's distributing the script from is in, and whether the script can be proven to have malicious intentions (a program which simply gives remote access to another computer is not necessarily illegal in and of itself).

thanks starbucks

crimes on the internet are a big deal guys

Yes it is.
And are traceable by to the computer's origin.

I've known of people that have done that. My solution is to let people know about it either by posting a warning on my website about it or asking someone else to do the same on my behalf, that being someone that I know would be willing to do so.

People generally respond favourably to such postings if they are to the point and factual rather than being of a more petty or insulting nature. Having the information on a site that people generally trust helps too.
