Voices as in... NPC voices? Without thineself making a modification to Diablo II (Voids ToS), the voices will never be changed unless Blizzard gets a wild hair up their arse and in patch 1.14 (If there will be after D3 is released). Yep... I hope D3 comes out before Patch 1.14.... :P This hope will most likely be ignored.

There are 6 computers/lap tops in my house and all but 1 have Diablo II on them and none of them who have D2 (Diablo II) on them have a virus. So, I'd have to say: No.
