    I have seen a few threads about this, but I want to get clear about a specific thing, before finally deciding whether to allow Windows back into my life.

    The used Macbook Pro I am buying has a dual boot system with OSX 10.9 and Windows.
    My question is, if the machine is booted up in OSX, and I go on the net, is it still possible for the Windows section to get a virus, even though I am booted in OSX?

    All help appreciated, thanks

    Nope, it's not possible.

    Windows uses an NTFS file system and cannot write to HFS+ file systems, which is used by OS X.

    So if your Windows side gets a virus, it'll stay there and won't go anywhere.

    Thanks for the swift reply. But ...

    I know that a virus can't travel to the Mac side, but my question was whether it is still possible for the Windows side to get a virus, even though the system is booted in OSX...

    It actually works the same way in reverse. OSX can't write to NTFS, so the virus couldn't be written to the windows partition.

    Nope, because the same argument applies.

    OS X can't write to NTFS.

    Not only do they use different file systems but Safari is pretty secure, you won't get a virus unless you visit some VERY shady websites.

    Luckily its apples and oranges and when you're in OS X, you cannot catch a windows virus and infect your windows partition. Nor can it hop over to your OS X partition if you do get one when running in windows.
