Real time scanning keeps shutting off in security suite

Question

real time scanning keeps going off and have to keep putting it back on

Answer 1

I, too, have the Droid 4 and have experienced the random shut downs, tho not as frequently as you seem to be experiencing it.  You said you did a factory reset - another option to try (that seems to help mine) is a system cache clear...
Power down phone
Hold volume up/down & power simultaneously until you see the Boot Mode Selection Menu
Use volume down to navigate to 'Recovery', use volume up to select
Should see screen with triangle and exclamation point next to an Android
Press volume up/down simultaneously to go into system recovery
Use volume rocker to navigate to 'wipe cache' and use power button to select
Once finished, use volume rocker to navigate to 'reboot system now' and use power button to select
It also may be a rogue app or a conflict with an app.  Have you recently installed a new app?  If so, try removing it ans see if that improves things.
How long have you had the phone?  Is it still within the one year manufacturer's warranty?
