Hi DavidR,
Excuse me for responding to a question meant for bob3160, whenever he comes online he will answer for himself I assume.
We adopted to use this in the cloud program around the same time, just give me a good feeling as bob3160 has similar experiences with it and a good nose for promishing novelties, it could be something for you as well because it so lean on the old cycles, much more than ThreatFire is, of which updating weighs heavy (at least on my XP SP3 machine), the scanning of allprocesses in memory and the system files is also performed quickly and adequately. Funny that we the over 60 guys have to like it, and that not a lot of youngsters installed it next to their av solution of choice, well in our case avast of-course, it also plays well alongside and recognizes Threatfire as a co-scanner, as it does avast. For now, I am a satisfied user of it,
