Application with name: ''manage settings'' trying to install itself on Sony Experia E1

Hi i have some strange problem on my Sony Experia E1 phone.

I have done 'factory reset' , and now some app with name: ''Manage Settings'' trying to install itself on my Sony Experia E1.

This happen when i turn ''off'' an ''on'' screen. I receive message to install this app, which is from ''unknown source''.

I always refuse this, but app insist to be installed again and again..

In security menu i was disable ''unknown sources''.

What should i do?

Or is this app some system app or something?

I have kit kat 4.4

All programs i was downloaded is from ''play store''.

I can't find that this program is related to any app i already have on phone.

Rickard thank you for your help, i found problem.

App with name ''com.game.arrangeblock-1.apk'' was problem.

I forget that i was inastall this game after reset my phone.

This game doesn't exist anymore on playstore , probably because of virus.

After i remove this app, problem is gone..

Thank you for all your help..

Alright, looking at this so called "application" it is actually a virus designed for the Android KitKat. The virus is a ransomware phone locker. If you download Malwarebytes Mobile from the Google Play store, give it a run and it should find it. I can give you direct instructions on how to do it. If you need any more help, please do not hesitate to contact me or add me as a community friend, I am here to help with your phone questions as wel as the helpful staff of the Sony Forums.
