I installed a game called Doors Room Escape yesterday (seems to be removed from play now). It changed my browsers home page from google to something that looked like google but had their adverts on it. It did this without asking permissions in any way.
Sophos Mobile Security didn't react in any way to this either, I was kind of expecting it to protect me from hijackings of this kind. Is this not something that it monitors?
Appbrain seems to still have this app, if you want to check it out.
