Ok here is the scoop. I apologize for this type of post, but I am curious, and admins if its not ok let me know. OK, I bought the nexus 7 2013 a week ago and absolutely love it. I let my younger brother borrow it for a day ( will not do again), and I found out that he went on pornography sites. Will this do any harm to my tablet, and from what I found I downloaded an app that does some cleaning called "clean Master", and i also use lookout. been using lookout for a few yearrs and love it. Is there anything else i can do to fix any harm that may have come across going to these sites?
