MRT and XProtect updates double install?
Just checked, it seems that the latest updates for MRT and XProtect have been installed twice, on April the 1st. I so this in System Information. It seems there are double receipts for each one. I wonder if they are compromised. I use the app Silent Knight to check and install updates for MRT and XProtect, because I can see the update, macOS installs them in the background.
