Hello my friend
Actually on that case you have a bit sufficient knowledge there since I taught you from prevention so likely your on intermediate level.
Hitman Pro and Malwarebytes were better to be stayed on the system. For Hitman Pro just make it portable for scanning and if you believe an FP detected just report it.
Addons you picked were really good to make your browsing faster, just add Adblock Plus for Firefox.
While IE9 just used the
tracking protection list since its has a built in security like SmartScreen Filter. (I recommend EasyList for tracking protection)
Also you are fun to experiment something on your laptop, then add Toolwiz TimeFreeze its really a useful application. All you have to do is activate the protection and everything will be undo once restart to drop the changes.
