I can't answer that because I dunno! I assume, probably incorrectly, that both versions (free & paid) would use the same engine.
Ah, that's why I was confused then! I'm too far north!
Ha, you're timing is amazing! No, it's raining! I am moving to a new server. Give it 1 minute and I'll have those copied over!
It's all more better now, see!
I guess the real point is that the tests used all the capacity of the suites, not just the AV:
"In this test, all protection features of the product can be used to prevent infection - not just signatures or heuristic file scanning. A suite can step in at any stage of the process – accessing the URL, download- ing the file, formation of the file on the local hard drive, file access, file execution "
Ah very good point! That's why we need that new i7 to run Norton with its AV, Firewall, Privacy Guard, Link Scanner, NSA Notifier, and some other stuff in there!
