The installation is pretty much very easy, I basically just click the next->next button. The user interface is very simple and friendly. The buttons are well layout and I immediately spotted how to run a full sweep just by 1 look. The scan is good also, I couldn't imagine how my other anti virus and anti spyware missed 3 trojan in my computer - worm koobface, tdss, and stinkbreath. It also catches a lot of adware and spy ware... hmm.. now i wonder if my old anti spyware is even running. It took 30 minutes to scan my computer with 200GB + 80GB hdisk. It detected 17 items and 38 traces. Finished the scan in under 40minutes (not sure if this is acceptable to others, but considering that I don't even notice it running at the background is good) It didn't hog my computer performance since I can still use a lot of my development tools while scanning (though I have a high specs laptop) .. It also have scheduler to execute the scan on your least busy time. In my case I set it to run every Sunday. I don't think I ever used the advance features that are included, but whatever, I only need the basic feature, shield, scan, and remove unwanted stuffs. I will definitely recommend this to friends and colleagues.
