I have a Alcatel onetouch 5020 smartphone. I wanted to use Norton mobile security but I have tried 2 times to downlaod it and as soon as it downloads it locks up my phone. The only way out is to push long and hard on the shutdown button and it does eventualy shut down. Then I do a reset and start from scratch once agian. It does have AVG on it but I always uninstalled it before I installed norton . What am I doing wrong?
