CLAM bugs:
  clamscan --mbox - < FILE ...vs... clamscan --mbox FILE
    Any of them sometimes return no viruses found.
    Under one user return viruses one combination and under another
    second.
Python bugs:
  zipfile read has no attribute to set filesize, whole file must
    be read into memory and then saved :(
