Could well be a false positive, but..
C:\Windows\SysWOW64\d2d1.dll Malware ( > Bitdefender . . . : Trojan.Agent.DNAY)
C:\Windows\WinSxS\wow64_microsoft-windows-d2d_31bf3856ad364e35_10.0.17134.523_none_93af86c5e6560604\d2d1.dll -> Quarantined
Initially it attempted to repair the file, but appears to have failed. Tried sfc scannow and DISM /Online /Cleanup-Image /CheckHealth, but need help in understanding the results. For example, sfc mentions the "/OFFLOGFILE flag" and I have no idea what that means. DISM reports "The component store is repairable.", yet there's no clue as to how to repair it.
Any help much appreciated. Thank you.
