Hey your concerns are legit but these hacking happens mainly due to you using your wallet on a public wifi, or having virus on your machine, or sharing your details like private key or seed with others. I would recommend you Electrum wallet if the total bitcoins value is less than 100 bitcoins, if it's more than Trezor wallet those are the most secured wallet, but use them only if you plan to hodl a big amount of bitcoins.
