I recently reinstalled Vista on my pc. I wanted to do a fresh install with an SP1 integrated image which I made with vLite, which had a lot of features removed so I have a lean 1gb iso. I have taken a base image of the install and am now installing security software. This is also my first real try at running with UAC on (with a few tweaks to disable the elevation prompt for admins) and so far I am happy with it and IE7 protected mode. I also installed Avira premium security suite with a free 3 month license offer (google search found it on comodo forums) and am happy with it - Avira IMO has always had great detection and a no-frills gui and runs light. I may buy it when the time is up. At this point I do not have any sort of HIPS and I would like some advice about what I really need in addition. There are 2 things I want to try as well - - adding an SRP on Vista - run Firefox in protected mode (by setting its integrity level to low) I don't know how successful these will be for daily use though. With protected mode, why do we need SandboxIE for IE? SandboxIE seems to have issues with FF3 from their forums. There are so many HIPS I read about (Defense Wall, ThreatFire, SSM, DriveSentry, Online Armor etc etc), but since UAC already adds a layer of defense, which one can best complement it without bothering me?
