"One thing you can do if you want to cut down on redundancy is to use the AIS Firewall, remove the OA firewall, and just use the OA HIPS and Run Safer."
FYI: I _am_ using the Firewall of AIS but I love the "Run Safer" mode of OA Free -- it is the ONLY thing I use at home.
Again, my workplace is a paranoid place for good reason -- with gads of internatinoal students, computer engineering students, and ordinary students torrenting, the place is a vector for every nasty you can imagine! But everywhere else, I use
AIS
OA Free ("Run Safer" only) plus
MBAM (on weekly schedule)
I don't know why more people don't incorporate the "Run Safer" option from "Drop My Rights" (free from Microsoft). Yes, there are a few user-mode rootkits that can elevate privileges but that simple measure gets rid of a LOT of issues. And it is really light.
Thoughts?
