I just did something I never thought I would do--bought a PC computer. My niece plays SWTOR. Wanted to be able to play with her. Didn't want to take up hard drive space by installing Windows on my rMBP. Opted to just buy a dedicated Windows gaming laptop, the Maingear Nomad 17 Ultimate (I'll use it for other games as well). Hasn't arrived yet. Has Windows 7 installed. Never owned a Windows computer before. Not planning on using it for anything other than gaming. Good idea to install Norton Antivirus? Things I should do when I get it to make it more secure? Again only plan on using it for gaming, keeping my Mac for everything important in my life. Not going to use this for surfing or email. What settings do I need to change out of the box?
