Questions in regards to Bootcamp and running HeRo on Mac

[Former-GM-Vanadis]

1) I don't really think you'd have to worry that much about viruses unless you do risky things, but just playing heRO on it should be safe enough. Still it's up to you, there are free antivirus software...

2) I'd go with XP, it's pretty stable for gaming.

3) I guess it should be possible to have it on a usb drive, though you might get some prefomance loss. It's not like the client is all that big either...
