How to Figure If an AV has Script Blocking

Sorry if this seems like an unworthy question but, I didn’t find where it says my symantec AV program did script blocking but I don’t want to conclude yet this program does not have it, especially when it’s huge and popular.

Thanks.

Norton has Script Blocker since there is a way to turn it off. Norton Support

You can not run Symantec (Norton) and avast! together as they will conflict with each other.
