Hi mirimir, How much bloated is it? Because I tested it a few months ago and it worked just fine, no 3rd-party software or anything. In fact, I used it along side with Avira Free and MBAM Premium, and performance in games like Battlefield 3 was the same as if I was using bitdefender free. Wouldn't HIPS+Firewall+Sandbox offer the highest security? Or is there some sort of incompatibility/annoyance between HIPS and the Sandbox?
