Is someone here who did it accidentally (or on purpose) to tell us if his hardware wallet protected (or not) his coins?
The hardware wallet will indeed protect your coins.
I tend to agree with this, and this was explained on the blog of the Trezor wallet. "
Fight Phishing with Trezor "
But usually, as I have heard, the clone wallet or phishing wallet like installing a fake version of the electrum didn't have any malware infection in your device, but the problem is the revise the code. When you make a transaction it will automatically send to their Bitcoin address and the reason for losing your fund.
In this case, to avoid that matter. Study of how to verify the authenticity every time you have to download and install any version of the wallet. Learn the PGP stuff.
