iPhone Virus? Strange Chinese Characters and .exe message

Hello,

I was wondering if anyone has seen this type of message on their iPhones when connecting to their computer :

My gf and I each have an iPhone and whenever we connect either of them to the computer we get the usual dialog box with our name on it but for some reason it also has some chinese characters on it along with some .exe filename. I see no reason for these to be there and I suspect a virus.

Can anyone identify this problem and whether I should be concerned?

Regards,

Anthony
