We need to mention it often and try to find solutions against scammers, hackers and criminals.
Hope for the best but prepare for the worst.
The solution, namely hardware wallets, is under our foot. Such devices keep private keys, the latter never leave their place. Thus your stash
guarded by HW will be safe even if your machine is infiltrated.
The most malware can do in this case is to change your destination address to "hacker's" one but you can easily spot it as most hardware wallets have the displays that show the transaction details.
The best HW are those that use airgapped communication with the software client run on computer.
My favorite HW which guards my stash is Passport 2 .
Find yours, DYOR.
