Sophos has a MAJOR pro, which is 24/7 support- some companies like that a lot.
But that said, the program itself is below par, and either F-Secure (the most complete and expensive AV software out there), or Kaspersky, or Avast, or NOD32, or finally Etrust/VET should work much better (plz note I do not mention Norton and McAffee, and this is not because I forgot to mention them...).
The revolution cannot be a lever, or an essay, or tablaeu, or embroidery. It cannot proceed mellowly, piece-by-piece, gently, devoutly, simply and humbly.
