the last time i used mirc 2 chat windows opened, which i closed..but would that have infected me??
Only if you clicked on a link in those chat windows, or copy/pasted something from them to your mirc command line. Unfortunately, spam like that is getting to be more and more prevalent in even chat channels lately.
RusselB's comment only means your mirc has the potential to be dangerous .. not that it is. Deleting your mirc for what it COULD do would be like scrapping your car because it COULD go 100 miles/hr thus violating speed laws in most locations.
