then you stop unzipped EXE but allow then inside zip (or similar)
my conf:
$banned_filename_re = new_RE(
### BLOCKED ANYWHERE
# qr'^UNDECIPHERABLE$', # is or contains any undecipherable components
# Next line must be commented out to allow exe inside archive file, markus
# qr'^\.(exe-ms|dll)$', # banned file(1) types, rudimentary
# qr'^\.(exe|lha|tnef|cab|dll)$', # banned file(1) types

qr'.\.(pif|scr)$'i, # banned extensions - rudimentary
