there is 1 trojan and you have to put your password and download it to get it. People people people, you dont need any virus protection cause you cant get a virus. THERE ARE NO VIRUSES!!! (if you use windows on your mac, then you could though. but windows sucks so dont get it)
but it would only affect your windows partition
