How Much Longer, Please?

[Take caution, please. I did not see if my question is already answered. My Norton software is Old.] How much longer will Norton / Symantec support Norton Antivirus for Mac v10.1.2 from 2005? I feel that I have withdrawn from this Corrupt & Bankrupt nation. [Those 2 "upt"s I like.] Upgrade, Upgrade & Upgrade. I as one say, “Poop!” By the-way, Norton Antivirus never has found a problem with my Mac. I’ve used NAV more than 10-years. Simply, like the sense of Security in this un-safe world. Thank you.
