Photo gallery and unwanted photos show up. How to stop?

[JPUSCPSCH]

I have had this problem, off & on, since I have had my bionic. In my photo gallery on the phone every now and then about a dozen pics somehow show up in the gallery. These are of animated sex postitions, pics almost like video game characters, some just have a black background with a "x" in the middle. How can I stop this from happening? Most apps for photo gallery let you look up pics so no one can see them with a password etc. Don't have pics like this on my phone. I consider this spam. I have lockout on my phone but it does not filter or stop these annoying pics that I must go in and manually delete? Any suggestions?:frown::angry:

How long have you had the phone? Did you add or update an app around the time it started? I don't know if Airpush Detector will help, but it's worth a shot.
