ahhh... that's the problem... i said i dunno if it works for the us version because i only play the german version... so i doesn't but i think gex will solve the problem

and... i haven't uploaded a trojan or something else... you get the virus alert because the programm is packed with themedia... and themedia was used for packing trojans too. so your kaspersky, norton etc. thinks that every programm packed with themedia is a trojan... but mhs 2.5 isn't!
