Battery Saver turning on Wi-Fi every time I open it and...

Updated Avast Mobile Security (Android KitKat 4.4.4 running on Samsung Galaxy S4) yesterday and I am not happy.

Now

  1. if I open Battery Saver it turns on Wi-Fi which is NOT supposed to happen.
  2. I get a notification there are 17 apps. running - I click to stop them and it does…one at a time slowly. In 5 minutes I have another notification saying I have 17 apps. running. I stop them again.
  3. When texting it now opens with Samsung keyboard instead of SwiftKey keyboard. In settings I make SwiftKey the default but next time I text it opens with the Samsung keyboard again! Not cool and never happened prior to Avast update yesterday.
  4. Battery life seems less than before the update.

I was loving Avast Security, Avast Cleanup and Avast Battery Saver before the update and recommended it to others.

As of today I am not in love and starting to hate Avast app.

Is there a way to uninstall the update and go back to being in love?
Thanks,
