It wasnt so much conclusions drawn specifically about you, but that in the majority of cases, ppl are searching for illegal files. Our refusal to help with that every so often generates a general discussion on that refusal (as you see).
The file you are searching for would prolly be harder to find on IRC, since sadly the majority of filesharers concentrate on movies/music/software etc. Also, since many networks have an AUP against filesharing, just asking could make them cranky.
i'm glad to hear that you are aware of the dangers of trojans/virus, and take precautions. A google search for funny cat videos would no doubt get you a million or so hits, and obviously you know to exercise caution clicking and downloading.
