Still a great decision. I use Ghostery, but I do understand why a lot of people don't use it. Everyone has their own personal preferences I personally normally back up a few important files to a USB and don't do a full backup too often as well. You must be playing an almost different game now with all those mods@Aerdian Ghostery is a valid option now that it is open source, but that does not wipe its past of being closed source and being owned by advertisers that sell your behaviour. I rarely give privacy software a second chance when they go against what they supposedly stand for. I will probably add HTTPS Everywhere, as I know that is still a great extension. My reasoning for not using Macrium is because I am particular about what I am backing up. If I am able to do something without automated software, i.e. copy and pasting files onto my external HDD, then I would prefer doing it manually myself. The only thing that I will agree with, mentioned by @harlan4096, @LDogg, and yourself, is upping my UAC level to max. I set it to default while installing 200+ Fallout mods, and I should probably return it to maximum level.
No one knows your browsing habits or tech skills like you, and only you know what you are comfortable with on your system.@LDogg because it literally doesn't. It is not exaggeration or stubbornness. On-demand scanners don't "prevent", they "fix". If you're using on-demand scanners to clean your PC, you're likely already infected or anticipating being infected by something. Realistically I don't need any on-demand scanners outside of my USB tools because they make zero difference in the machine's overall live protection. As for extensions, as long as I'm regularly clearing my cookies and deleting my cache on exit, uBlock Origin is the only thing I would need for safe browsing. I used to use HTTPS Everywhere in the past, but even base Chrome now is pretty good at informing you when you visit insecure sites.
Edit: I'm putting strong emphasis on having a slim configuration.
Ghost edit: UAC set to default (again).
