MT's purpose is to prevent infection by any means possible & explore alternatives using our intelligence & experience - I understand that using lock-down systems are one way to any degree, safe browsing is another along with others including multiple backups with one in an alternate location. Feeling the more is merrier for me is not my solution, for information I don't use Facebook & avoid most other so called social media.
I do use carefully chosen programs to keep me as safe & light as possible including Macrium Reflect & Shadow Defender & the latter is useful when others use the PC 's & they don't even know it's on, Ublock also plays it's part & VS - Don't forget the original question BTW ~ The is not one way or your way & others are wrong, that is simplistic & frankly somewhat egotistical ~
