First i don't know if NOD32 protect the mIRC with their firewall but i know that there are many scripts or remotes that can delete files or give someone access to insert into your system, now i told you my opinion to do, And i am not sure that if anyone want to insert into your system to use the mIRC, it is very difficult but for someone who knows very well it is easy. Anyway just disable your DCC and have one GOOD firewall installed into your PC and you will be safe, If you want my opinion try to use one good firewall
(ZONEALARM) i heard very much about this program and is good!, Also if you disable your DCC then noone can send you any file i thing this is good!
EDIT: Check
this remote about BACKING UP your remotes.
oh so it means if chat request and get files request section in IRC option is disabled then even if my scripts allow potential hackers to find their way to my folder/files and PC through using remote commands, it won't be possible for them to be connected to my IRC and do as they want?
I used your advice and disabled chat and get file request in my DCC. also adjusted NOD32 in a way it scans and monitors IRC when it is connected. I think it should be safe for now, right? ^^
thanks so much for your great advices and also the link for backing up scripts dear westor. *hugs* I am reading through the posts there right now, trying to learn more
