...Or password encrypted RAR Files...?
It's just an extra step that might decrease the likelihood, but will more than likely end up annoying more people than viruses it prevents...

How does it deal with archives?

Can it detect signatures within before they are opened?

I would properly prefer Fortinet...

By the way, can they really do it packet by packet? How could they know what's the 1st part of the code mean, when the next/last part of it still on the other side of the server?

I still prefer Fortinet... (even for home)

Intrusion-prevention systems (IPS) are hardly new devices, nor is the worm hole routing. I take this device is aimed at the SOHO market?

IPS can be fairly annoying because it bins false positives, which leads to so things not working with no reason why.
