Is it a good idea will version 5 of Vs to leave always on ?
I use Always On without any problems at all. It is my preferred mode. Smart, Autopilot and Always On are simply a matter of preference. I sometimes switch to Autopilot, but never Smart. Autopilot functions more like an AV (except no auto-scanning files), but is also dependent on other settings.
If you are asking in regards to the number of pop-ups you will see, this depends more on your chosen overall configuration, including Security Posture and other settings. "Aggressive" will give you the most, followed by "Moderate", etc. The number of pop-ups you see will also depend on other settings available in VS Pro.
@Arequire's configuration posted above is a good example of a configuration that will result in many prompts.
I always suggest users become very familiar with the GUI in order to understand the many ways to use VS. Experiment to see what setup suits you. You may always post questions here, or at

Edit: Autopilot mode + moderate security posture = most like an AV
