Best opinions (in my opinion
):
1. There's nothing magical about Prevx, it just monitors several areas of the system that are often manipulated by malware, but does require extra user interaction when activities (often legitimate) are detected.
2. Prevx is generic detection that requires no signature updates. I would guess that is uses behaviour monitoring and some sort of heuristic anylisis to prevent malware infection. It also monitors registry activity, prevents buffer overflow attacks, and prevents dll modification. This software is ment for prevention as opposed to detection.
3. Prevx Home doesn't rely on signature-based method but detects potential attacks by their behavior so it can detect (theoretically) malware that can bypass your traditional anti-virus/anti-spyware/anti-trojan.
About being free...
4. Prevx makes their money from their corporate product and soon to be release Pro version of the home product. It's almost too good to be true, but it's true and pretty damn good.
