If you know what you are doing, even a separate USB stick (with a live OS and so on) will do.
But if you are a newbie and not that knowledgeable with computers too maybe, then hardware wallet should be your friend.
I used WinRAR many years ago. Now I see it as an outdated software, 7zip being superior. But I know many people that are so used to WinRAR they still have it. Thanks OP for the warning.
Like I used to use WinRar since I first owned a PC and didn't even have the intention to replace WinRar.
But seeing that Winrar is quite vulnerable like that, then 7zip is a good choice for me to switch from Winrar. Of course there will be a few more vulnerabilities, rather than risk it is better to use one that has been proven safe.
