I install this app in my mobile and and use it for 7 days. I am totally disappointed after using this app in my mobile. This app shows that he will not take any charge forever. At trail period this app gives only scanning option and no protection is there. After upgrading or after purchasing this app suddenly stop working. It crash every time whenever I scan the mobile. I donot know that this app really gives interent protection by hackers. This app makes me fool and I am totally disappointed after using this app. I want my refund.
