Is the antivirus activated in the proactive configuration by default?

I’ve chosen not to install the antivirus as I already have one running on my computer. Nonetheless I’ve noticed that I can enable it through the configuration settings. So I was wondering if it is activated also at the proactive configuration by default.

Thanks for your quick reply. I don’t really know if it is really activated but when I choose the antivirus security configuration it says that the configuration has been activated successfully. However, now you mentioned it , I don’t see much of a change in the summary (or anywhere else). It is only configured as antivirus security. I have not installed it though.
So you say that (even if it were installed but not activated) it wouldn’t come up automatically with the proactive configuration, right?
