I have a one year old Nexus 7 and recently my tablet acts on its own. It starts to action commands without me doing anything. The only way I manage to recover control is to power it off and on again. This problem has become much more frequent in the past few days.

I've a Kaspersky license and it hasn't brought to my attention any threats. Prior to having Kaspersky installed, I had McAfee Security, but I was never able to uninstall it because I can't deactivate its device administrator status. I don't understand why.

What can I do to overcome these issues?

  • What exactly does it do without you doing anything?

  • It causes different apps to open and selects options and menus without my intervention. It hasn't yet written things on its own though.

You should go to McAfee settings there is an uninstall option somewhere in the settings , on pressing that McAfee will ask you if you would like to remove it from device administrators , continue with the uninstallation from there.

And , for your immediate issue , I think your device has got a serious virus/malware or may even have been hacked , which is causing remote control by someone( I don't know if I am exaggerating a bit).

So firstly try killing all the network connections , manually remove sim card (if your device has it) and turn off the Wifi router and then observe if those issues persist.

If issues persist factory reset your device , but prior to it take a backup of all data(or I think you should not because it will carry the malware with it so do accordingly).
