I recently received a tablet as a gift and need to get some sort of security on it, but have no idea what's best. I attempted to download AVG free which told me it was rooted and something about contacting the manufacturer about getting it unrooted? So I panicked and didn't go ahead with the installation and now I'm not sure what to get. paying for one is fine but as the tablet itself wasn't mega expensive it doesn't seem worth spending too much on it, but on the other hand I want to use my email, browse the internet, etc. without being worried about it being hacked. Any advice will be most gratefully received, thank you.
