Allow auto-update of only a single app Is it possible to auto-update selectively? For example, if I want to allow an anti-virus app to update, but no others. Can this be done? Android 4.0.4
Yes, it's possible, but very time-consuming.


Open the Google Play Store, go to Menu -> Settings.
Tap on the "Auto-update apps" and select one of the two "Auto-update apps" options to enable it.
Go back, then go to "My apps" section, locate the app you want (e.g. anti-virus app that you mentioned) and tap on it once.
Now tap the Menu button and the first option should be the "Auto-update."  Ensure the checkmark is present for this app.
For all other apps that you have installed, you will need to follow steps 3 and 4, but this time disable the "Auto-update" setting by unchecking it.
