windows defender

hello,
I helped a friend install win10 on his laptop. everything went fine, but I noticed that windows defender is still running scans and things like that, even though he has webroot installed.
I want to just use webroot. so would I disable defender simply by disabling the service? I thought it might be trickier than that since malware or viruses could easily do the same.
if it is just disabling the service is it called windows defender? Again I ask because that sounds too easy.

You can just disable the Windows Defender Service.  As long as  you have other protections you're fine.

Here are the proper steps to disable Defender in Windows 10

Steps to Disable Windows Defender
1.Go to Run.
2.Type in ‘gpedit.msc’ (without quotes) and hit Enter. This will open up a new menu, where group policy editor options are listed.
3.Head to the ‘Administrative Templates’ tab, located under ‘Computer Configuration’.
4.Click ‘Windows Components’, followed by ‘Windows Defender’.
5.Find the ‘Turn off Windows Defender’ option, and double-click it.
6.Apply your changes before exiting the GPE menu.

And in this blog it shows how to disable is using the registry.

Go to Start, Settings, Update and Security, Windows Defender, and disable it. No need to edit the registry unless you wish to .

Then repair or reinstall you Anti Virus.  Why?  Having Defender run at the same time as your regular anti virus is probably causing high CPU usage. Just disabling Defender won't fix this. Repair and/or reinstall of your anti virus should result in lower CPU usage.
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

John, please read http://www.tenforums.com/tutorials/3569-windows-defender-real-time-protection-turn-off-windows-10-a.html to see the difference. Using GPO (or regedit) turns it off permanently, your way only temporarily as noted on my link.
JohnBusiness Consultant (Owner)Commented:
Windows Defender have been permanently OFF for nearly the whole month I had Windows 10. It has never come back on.
JeffBeallAuthor Commented:
thank you for the help. for me the regedit worked. I didn't have gpedit, I think because it's home edition. I couldn't turn the service off in services, it was greyed out ( even as admin ) and in defender, if I turned it off, on reboot it would just come back on.
McKnifeCommented:
Yes, because you run an AV software that is recognized by  defender. His isn't.

Follow up:

As McKnife noted or alluded to, Symantec Endpoint Protection turns Windows Defender OFF. That worked for over a month, and then it seems, after al the opportunity in the world, Windows Defender somehow got in the way after Patch Tuesday just past. I repaired SEP again and have now also used the GPO above turn Windows Defender OFF.

We will see in a month after next Patch Tuesday.  Thank you.
