First I have to ask why you think it was hacked?
Additionally, if you chose the version of a reset that tries to keep your personal data on the phone, then it really wasn't reset and nothing added to your device (if anything was) would have been actually removed. To resolve that you would really need to do a "Hard Reset" which will completely wipe the device of what is on it and then restart it as it was when first gotten. All your personal stuff, and anything added to it, would be gone.
NOTE: Doing this will clear 'all' the data on your phone, so it is suggested you not choose this option unless you have to, or aren't worried about losing anything on the device.
Be sure you back up any data you want to keep, to a computer or cloud...
