I am new to ubuntu and after some month and a half running it side by side with Windows 7 I decided that it would be my main system, and so I just formatted the machine and installed it as the only OS. However, I still need to run some stuff that don't have options for ubuntu, just like netflix or to manage my Windows Phone system.
As a solution, I am thinking about running Windows XP on a VM, I just installed VirtualBox, but after some searching I saw that the best perfomance would be obtained if I install the Guest Additions. I don't intend to share folders, although I am concerned if installing guest additions would somehow expose my Linux system to Windows viruses. And I will probably use the network through windows xp vm either, but I won't surf on the web, I'll only eventually use netflix.
Well, the question literally is, as said on the title, is windows xp running on a virtual box with guest additions harmful for ubuntu? Does it may lead to viruses issues?
