Since getting rid of Groove Music off my computer I am now getting Windows Defender warnings that I am receiving serious 'Trojan' threats. Up to 10 a day. It says it is removing them but when I check they are still listed and I delete them by hand. There is some evidence that some functions on my computer are behaving strangely. Also occasionally Windows Defender asks me to restart the computer and often that is an inconvenience.
The Trojan is listed as Trojan:win32/skeeyah.A!rfn
