Chrome and gamebooster for me.
I tried comodo dragon and it wasn't that good at all. But everyone's different.
MickAnderson: Also, I've just installed gamebooster too. Is there something I should be doing to switch it on and off when I am playing and not playing, or does it just work automatically?
I've got my game booster as a desktop icon and click on it before i start the game. Big red button appears on my screen, click that and away you go.
The only problem i got now is getting the eye's focused :-)
