"Also I dont have anything to hide other than I download stuff so its not worry for me at all"
What do you mean by you "download stuff"? If you're downloading mp3s/movies/software/etc, then you would have something to worry about, as downloading such material is illegal. It's also not what mIRC is meant for, aswell as a good way to get a virus.
On the other hand, if you're just getting picture/text files from a friend, then you wouldn't have much to worry about.
