or manually open your mirc directory find the file called mirc.ini
scroll thru it and find a section that looks like this
[afiles]
n0=aliases.ini
[rfiles]
n0=remote.ini
n1=remote.ini
n2=script.ini
remove the name of the .mrc file from that list under [rfiles]
only do this with your mirc CLOSED... once done restart it and then u should be free from that. DONT forget to DELETE the BAD file from your pc
