You could do it like this (check the comments):

[...]

# Check malware, continue on "defer"
warn malware = */defer_ok
      set acl_m0 = 1

# When $acl_m0 is set here, there is either
# a virus, or there was defer due to an error.
# In the former case, $malware_name must be
# set, in the latter, it is unset.
deny message = Contains virus ($malware_name)
      condition = $acl_m0
      condition = $malware_name

warn message = Error while scanning
      condition = $acl_m0
      !condition = $malware_name
      control = no_mbox_unspool
      control = freeze

[...]

This assumes you do not use $acl_m0 for other purposes.
