Welcome to Android Central! I doubt the com.samsung.android.MtpApplication app is of any concern, unless the phone has been out of your sight and you think someone else might have hooked it up to a computer without your knowledge.
The only way that your Google password could've been changed without your knowledge would be if someone else had access to your account. Does anyone else know your passwords? Are they easy to guess? Do you customarily log into your Google account on public computers, and then fail to log out?
