That's contrary to the threat model ('it is just a scanner'). (Plus you can't do it. mmap. Of course you can pass viruses between two cooperating applications... and you can do it through filesystem, too. And you probably can make un-cooperating network server serve viruses, as long as the network server uses mmap.) This is the thing that makes antivirus ugly, its unique to the antivirus, plus it can't be done. I.e. bad goal.
