Hello everyone - I'm a newbie and i would really appreciate any help or assistance on the issues I'm having with my Hudl. This is a second hand one i bought and up until last week it was all fine. Then BAM!! It starts to go hey-wire with porn apps. each time it switches on it's trying to install an adult browser and a lot of apps such as sexy hot wallpaper, love beauty, sexy girls apk,and many others...i have gone into settings and have unticked unknown sources re advice online, but to no avail. please help...I'm not very techie minded. Thanks in advance.
