"I have been looking at the files involved in this Microsoft virus and have identified it as svchost.exe - k netsvcs -p. I am now trying to block its internet access via Norton by locating the file in firewall and adding the file from its directory. I will let you know if this works."
It should be noted that the new WaaSMedicSvc at C:\WINDOWS\system32\svchost.exe -k wusvcs -p is according to google Search "The Windows Update Medic Service is a new Windows Service introduced in Windows 10. ... Windows Update Medic Service (WaaSMedicSVC) enables remediation and protection of Windows Update components. This means that even if you disable Windows Update related Services, this service will at some point in time re-enable them." This addition to Norton will hopefully take care of this too as it should block svchost[1] from the Internet
