1. is this product just like Prevx 2.0? has a scanner, seems to have a user database, seems very similar to me to Prevx 2.0 2. is the HIPS good/better/worse than Prevx 2.0? 3. resource usage and features, how does it compare once again? just curious, thanks. also, i noticed the licence is just £10, how long is the validation date for?
