But why block miners and cryptocurrency wallets?

Reason for blocking crypto download files

Not just specific miner but your browser antivirus software reports almost every miners as virus.

ETH Miner, Claymore Miner, NiceHash Miner, Honey Miner, CCMiner, XMR STAK, XMRIG etc. Most new users think the warning is real. No they are not. In fact most of the miners and wallets do not contain any virus or malware.

The reason why Chrome and Firefox marks such files as malicious is the same reason as Windows defender and anti virus blocking miners.

Mining software’s contain scrypt that uses computers CPU power to mine cryptocurrencies. Back then hackers make botnet of miners and deploy into users computer without the knowledge of the owner. They then control the CPU power to their own advantage. This is the main reason why every mining software’s are getting blocked.

For wallet downloads it can be some other reason. Your wallet file will get blocked if you download it from host site that is unknown or untrusted. It will be blocked If the site or file’s publisher cannot be verified.

In most cases it simply blocks files from sites that are not using proper SSL certificates or https URL.

You can simply ignore the warning, discard the pop up and download the file. However here are few points to note.

Safely downloading files

It is never recommenced to download and run miners on same computers where you have wallets installed. It can compromise your wallet security. Either use a dedicated mining rig or buy a hardware wallet such as Ledger or Trezor and move all your coins there before you use your PC for mining.

Never download closed source miners except few reliable miners such as Claymore Ethereum miner. But then use such miners only on your mining rig. Not on your Personal Computer.

Before you download and install DYOR and make sure you are downloading the right file and from the right place. Additionally you can verify the checksum.
