Good Day Longvic
The detection of "not-a-virus:RiskTool.Win32.
BitCoinMiner " is the coin miner scrypt_86x . This is the miner build into the wallet itself which always have been picked up as a virus due to Microsoft and numerous Antivirus programs condemning the use of crypto currency . Please do look up on Wikipedia as all wallets new and old contain this miner as this allow the user to mine with the wallet by setting the console to setgenerate true . 80% of miner programs will contain this as the use of Sha256 encryption.
Hope this finds you well
Kind Regards
