I am not sure what you are using for AV or whether or not you are behind a firewall but IDE protecton per se seems to be heading to the overkill zone, IMO.
Also no mention of what your O/S is and assuming it is XP-SP-2 with it's own firewall enabled think you are adequately protected.
OK, I gave Prevx a full month trial (well almost a month) and I noticed (1) it didn't play nice with other programs (Spyware Doctor and MSAS) and (2) could not see, beyond registry protection, what value it was adding to my security suite.
I have reenabled MSAS and Spyware Doctor real-time protections and disabled (yet again) Prevx Home. Already have noticed smoother running simply by disablying Prevx from my system.
In theory I like the idea of IDE protection, but not sure that Prevx is the product I want on my particular system. I've used it on and off for 5 weeks now (total enabled time) and I always felt my computer ran choppy whenever it was on there.. all the alerts were a pain (a necessary pain I understand) and, except when downloading something, I never saw any indication it was doing anything (which is not meant to imply it wasn't).
How necssary is this program? I have plenty of other programs running to protect my PC (just for real-time protection I am using Spyware Blater, Spyware Guard, Spybot immunization, Win Patrol, and the aforemention MSAS and Spyware Doctor real=time protectios, which I've reenabled after disabling Prevx).
Do I need a registry protector beyond Win Patrol (doesn't report in real-time, may take up to a minute to discover any changes, but in essence still provides similar protection to Prevx and plays much nicer with my system)?
(PS I am thinking of adding DiamondCS's Process Guard to the mix, anyone using this and can they please comment on it).
