I checked a bit info on trojan.generic virus ... Throught I couldn't find any info on what that particular trojan do. It would seem that type of virus is very common to p2p technologie. It could do anything from erasing your hard drive to stole your personal information. Usually very hard to remove.

I find this rather threatning since it infected official data, that would also mean it spreading like wildfire and would most likely download itself on any new user that try to patch. I don't really see what we can do ,if I cannot play safely that mean Final fantasy XIV is dead to me. The only thing that can be done would be for SE to change the the patch download location with the uncorupted data but even that there no garanty it would not come back .

Well I do hope SE prove me wrong through I love that game but as I say safety come first, I honestly feel like they rushed that patch instead of doing it correctly I wouldn't mind have waited longer for the patch specially if that patch mean I can't play the game anymore.
