Hi! I have installed 10.7.3 from 10.6.8 ADN it runs fine, but I think that there is a small down in performance. Should I clean install Lion? It's the better way to install it? I also want to skip things like the Flasback Trojan... Anyway, which one is the best way to the clean install? Create a install disk or USB, or Internet Recovery Install? Can you help me?
