It's not quite that simple, since Brian doesn't want to defer when
the scanner *is* running.
Set an acl variable after the malware=* in the warn stanza, then add
a defer stanza following the warn which is conditioned on the acl
variable not being set. Something like (untested):
warn
message = X-Virus-Warning: This message contains malware ($malware_name)
malware = *
set acl_m0 = scanned
defer
condition = ${if eq{$acl_m0}{scanned}{no}{yes}}
malware = *
