A- Up until recently I used Prevx in combo with Malware Defender (MD). Now that MD is going down the road to perdition, as blazed by DiamondCS & BOClean & ProSecurity (et alia), I just lost my taste for MD right now. B- Therefore, I am looking for a FW with HIPS or Behavior Blocker, as per topic of this thread. I am running WinXP SP3. Free or paid (up to ~$60 or less). C- The ones I have tried & do not want to use are... 1- Online Armor (it's too heavy for my aging computer) 2-Comodo FW w/D+ (I know I am the exception, but I find configuring D+ is simply too convoluted for my pea brain. It can get it to work pretty much the way I want it to do, BUT it's like riding a horse all day with the wrong size of saddle -- it gets me there but it's still a PITA.) 3-Private FW w/DSA (the FW needs a learning mode -- or maybe it's me that needs a learning mode. Also, DSA is a tad outdated.) D- The preceeding may be the only FW/HIPS available right now. If so... such is life.
