hello all,I'm new to this board and I need some help,recently I installed mx player from the play store.My niece wanted my phone to watch a video so I let her borrow my phone...she ended up telling me that there was a popup that said 1 virus was detected and to scan and remove it,so she clicked the link and it took her to a website saying to download this to scan your phone,after that avast popped up and told her that the application that was trying to install was bad so she hit the option to delete,also I have the unknown sources application unchecked cause I don't download anything unless its from the app store.I didn't see any new apps or anything installed on my phone and nothing seemed to be messing up or glitching..also my phone is unrooted.I did a factory data reset just to be safe...so im wondering would a data reset get rid of anything if i had it? link.Ijust want to be sure nothing got on my phone...thank you for your time.
