Samsung galaxy 3. Internet opens on its own or play store. After 3 months of using anti virus and scanning I have finally found the culprit. CM ANTI VIRUS as well CM app lock or anything owned by CM like QuicPic. Uninstall and you will no longer have the issue. I have not had the issue since I uninstalled them all. Even though CM antivirus was to be good for your phone IT ISNT!
