I'm writing this because I'd like some advice from you about some problems of my smartphone.
Basically, last night before to go to bed, i've turned off my wi-fi and mobile connection from my smartphone, leaving the phone itself turned on.
This morning after getting again the phone, i've noticed that the wi-fi was turned on again, and there were notifications from my Avira antivirus recommending me to install another app when I connect to not safe or public wi-fi's.
So this means that the smartphone connected during the night to some anonymous wi-fi by itself..
I would like to know if it depends because of some malware and how it is possible to resolve it.
