"Notification Error"

[Guest Junez]

"Notification Error

Cannot Execute \Storage Card\Midway Marble Madness\ Marble.exe"

I seem to get this error everytime I turn my phone on and off (by that I mean standby, touching the off button once to reserve battery levels right)

I've Googled it and it happens with other softwares apparently, I have no idea how to get rid of it, or how it even got there as it's only my younger sister who plays games on this.

It's an MDA.

Thanks if anyone could help
