Windows 10: Turn Windows Defender off when using Windows 10 Backup Program?

When using Windows 10 built in back up program to make an image, can Windows Defender continue to run or should it be turned off during the process?

I have been making image backups with WD running, but then I have never had to use the backup to restore an image. Just want to be sure the backup will work if needed.

Thanks

PS: Same question as respects my other system with Windows 7 but using Norton Security. Should the AV be on or off during the backup process?

Windows 10 Anniversary Update Issues

Problems with W10 Anniv auto update:

Mom's: (x58 Xeon 5677) Windows Defender was not turned back on automatically (it was "on" in the 1511 edition) and she had a Trojan. Full system scan to eradicate.
Her Epson printer was knocked off, had to uninstall by Device Manager pull USB cable and reconnect cable. W10 did the rest.

Step-mom's: (HP pre built) Windows Defender not turned back on by default. Her USB Seagate Expansion Drive 2Tb was offline so all backup routines were halted. Had to rerun backup plan. Had her do a full virus scan.

Step-dad's: (Dell Optiplex tweaked upgrades) Windows Defender not turned back on by default. Full Scan.

 

Back to Windows 10 for me!

msmpeng.exe is Windows Defender(a completely useless program in Windows 7). You can get rid of it by turning off Windows Defender in the Tools section in Windows Defender, and then going into services.msc and disabling the Windows Defender service.

 

Windows 10 Defender - How to make it default to task bar?

Using Windows 10 and currently I am using Defender for anti virus. For whatever reason Windows Defender does not show up in the task bar unless I search for the program or right click and scan a file/folder. Is there a way to force Defender to show up in the task bar at start up?
