Just DL'ed their 30-day evaluation copy, and it seems like they're
competing directly with Spybot now.

Any thoughts and comparisons from the experts here?

Do I really need to run Ad-aware, Spybot, SpySubtract, and AdSubtract?
Throw in NAV for good measure, and I'm spending more time on this
than anything else on the net these days.
