Some of the photos in my gallery are being replaced by other photos of mine and it looks like the ones replaced are deleted while the new one is just a duplicate. Around the same time a photo started showing up advertising a free "dolphin browser" in an album titled "my album." Sometimes the browser windows that I have open all close down and a google window opens. Any ideas on what's happening and how to fix it? I can't find anyone else so far who's had this problem.
