How do I disable security scan on MS edge?

Question

Setting "Microsoft Defender SmartScreen" does not works.

It's disabled, but it does not affects - all downloading files still go to 'scanning for viruses'.

I tried to restart browser.

Windows/browser info:

Answer 1

Although it is not recommended to so due to security reasons but if you are really looking for the solution, then disabling Anti-Virus software might be one option( you can look through specific AV vendor's documentation for how to achieve that and disable only specific functionalities), but it will leave your device vulnerable from security perspective

I have no any third-party AV soft, and in any other browser such behavior missing, so the problem in Edge.

Answer 2

Just because you disable Smartscreen doesn't mean you've disabled your antivirus software from scanning downloads. Smartscreen is a pseudo-webbased service that checks your download against lists. So yes, you unwisely have it turned off.

What you see scanning the download is the browser tied in with your antivirus software.

I have no any third-party AV soft, and in any other browser such behavior missing, so the problem in Edge.

Or is this means that Edge has some relationship with Microsoft build-in AV soft and calling it when downloading...?

Answer 3

Anyway this setting looks very strange, because it's saying 'Help protect me from malicious sites and downloads with Microsoft Defender SmartScreen.' - nothing changing when this setting on/off... it's confusing and looks like does not works.

Answer 4

>May I know the scenario where you would want your AV software to not scan the file?

The scenario is that Edge typically takes a very long time (up to several minutes) to scan downloaded files, even when the files are tiny.  It's both patronising and inconvenient not to be able to switch off a virus scan when 99% of the time the files are being downloaded from safe sources.  The AV system is use on my PC is Defender, which I thought should be perfectly tuned to work with Edge, but obviously not.

Answer 5

I haven't had such experience with Edge. It is a standard behavior for the browsers to allow AVs(whichever is default Anti-virus on the system) to scan any new downloads before user can access it. Seems like AV is taking long in this scenario. 

If you really want to change the Microsoft Defender's behavior, then something like https://docs.microsoft.com/en-us/powershell/module/defender/set-mppreference?view=win10-ps will be helpful for you (specifically -DisableIOAVProtection). Again, this is not recommended as it creates a security loophole. If it's just the archive(.zip, .cab, .7z) files which are having the issue, you may try -DisableArchiveScanning option
