Is  "[failed] com.apple.xprotectupdater.plist" an error that I have to correct ?

Answer 1

This is a fairly basic daemon that should instruct the launcher to open the /usr/libexec/XProtectUpdater utility every 24 hours. You can try loading it manually by running the following command in the Terminal utility (provide your password when prompted--it will not be displayed):
sudo launchctl load /System/Library/LaunchDaemons/com.apple.xprotectupdater.plist
The daemon's contents should look like the following text, so locate it in the System > Library > LaunchDaemons folder and compare its contents to the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
          <key>StartInterval</key>
          <integer>86400</integer>
          <key>Label</key>
          <string>com.apple.xprotectupdater</string>
          <key>ProgramArguments</key>
          <array>
                    <string>/usr/libexec/XProtectUpdater</string>
          </array>
          <key>RunAtLoad</key>
          <true/>
</dict>
</plist>
Alternatively you can test the utility being referenced by the daemon by running it directly in the terminal (just copy and paste the following into the Terminal):
/usr/libexec/XProtectUpdater
