You could connect your Trezor to a public Windows XP machine at a hacker conference and you would still be safe. The point of Trezor is as a firewall from the stuff that happened to your brother (sorry for his loss).
Just… for the love of God… [read the manuals](https://www.reddit.com/r/TREZOR/comments/s8w028/lpt_read_the_manual_no_seriously_read_the_manual/). Manuals have good tips and advice like „Don’t send your seed to Elon Musk…. regardless of what twitter says“
If you just follow the manual you will be fine.
