now, i might be wrong so forgive me if i am, but dccman.exe sounds VERY suspicious. Sound like one of those stupid so called "dcc accelerators" people try and send u which are actually viruses/trojans/self replicating scripts.
I've only just woken up so i can barely see to do any research on it, but i'd suggest removal of dccman.exe personally. If its in the mIRC dir, definatly delete it, otherwise do some research on it 1st.
