I woke up this morning to my 2nd message in three months that Verizon's Security & Provacy App has found a file infected with Stagefright.H in a long pathway that contains "Instagram" in it. Both times I have chosen to remove the file (per guidance of the app), and taken screemshots of the message.
I can't seem to find any current information (since 2015) on this issue and am not sure if I am removing the threat completely by removing the file or of I need to take further action. Also, it is not clear as to whether my phone has been patched or is still vulnerable to new infections.
Help?
