Ok I felt this would be most appropriate here.

Heres my problem, This only happened recently, when I am download off an bot on IRC, after the file has completed download, the file size become 0KB and when I try and open the file, it doesn't work. Anyone know how to fix this.

i would say, get rid of the virus on the pc thats deleting the file, and stop downloading programs that contain them of irc.

I did a full system scan and nothing was found.

well it isnt happening to anyone else so i really doubt its mirc doing it, not on its won at least. Maybe some rouge script u have?

It might even be your Anti virus, detecting a virus and erasing the file?

Well I deleted all my scripts, but it still didnt fix it, so what I did was chage the directory it downloads to, and now everything downloads fine.
