Norton blocked an attack by Miner.BitcoinMiner Activity 9 repeatedly

[Abishkar]

So I am being repeatedly notified by Norton that they blocked an attack by Miner.BitcoinMiner Activity 9, and it says it started from location of dllhost.exe. I have Malwarebytes so I ran a scan and it detected 12 potentially maliciious files and I quarantined all of them and deleted them since I couldnt recognise them. but Norton is still spamming those reports. what to do??
