I am looking for practical steps/software I could use to protect from hacking attempts.
90%+ attempts will come from - email links - dodgy website downloads - dodgy browser plugins.
So for email links, use Mailwasher as well as CONCENTRATE on what you're doing and what links you're clicking.
For dodgy website downloads, don't go to dodgy websites and certainly don't download anything.
For dodgy browser plugins, less is more. All you really need is uBlock origin, HTTPS everywhere and perhaps Privacy Badger. All the others, unless from a very well known company, don't install.
Keeping yourself safe is really just common sense. However, who's also on your network? If you've got young kids, they're a risk because they might download something. If you live with elderly parent(s), perhaps they live in an annex, they're a big risk as well. If so, you want to get an expert in to setup different networks for your house, your trading setup is on one, the others have different one's etc.
