1. Background
Windows Defender (WD for short) is really annoying. It often reports to you that the file you downloaded is a virus. It doesn’t tell you whether it is actually a virus or not. It deletes it without even asking.
In addition, the data shows that WD will also perform scans at inappropriate times, causing the system to slow down (it will not be executed at a suitable and idle time).
Note: When you download a file in chrome and it is deleted, this is not the fault of chrome, it is caused by WD.
As shown below, regardless of whether 3721 WD will delete your stuff directly without asking.
According to the information on the Internet, chrome deleted your files, so modifying the configuration for chrome will not work. If the following does not work, download and delete your files as usual:
Settings->Privacy and Security->Security->Safe Browsing, change from "Standard Protection" to "Unprotected"
2. How to turn off Windows Defender
There is a lot of information on the Internet, and sometimes different Windows minor versions, such as the same win10, may be a little different (I really, really hate changing the Windows menu, so I use a MacBook (but sometimes I need to install a win virtual machine) )
Method : Install Tencent Butler or 360, WD will automatically shut down after installation. If you feel that the butler is cumbersome, just turn off the startup of Tencent Butler and exit it, and the WD will still remain closed.
In order to save its life from being investigated for monopoly, Microsoft automatically shuts down WD if you install anti-virus software.
I have actually tested Tencent Butler, but I have not tried 360, and I will not install rogue software. After installing Tencent Butler, I don’t need to turn off the startup and exit Tencent Butler.
If the software you downloaded in this way was automatically deleted originally, you will now be prompted and you can choose not to delete it, or you can add it to the trust zone.
3. Why do I recommend installing a third-party housekeeper/antivirus instead of other methods? Stop fussing, just use a simple way to solve the problem
Because closing is really too complicated,
Some people say that it is not possible to close it with one click using a third-party tool? The problem is that the tool you download will be exposed to viruses and deleted by WD, so you have to temporarily close WD before downloading.
To turn off WD, there are many steps and information on the Internet. Different versions of win10 have different operating methods.
There are some reorganization strategies (it is said that after the changes are made, they will be repaired. Anyway, after I tried restarting, the options I changed were restored by win).
Some changes to the registry.
Some people don't have that menu or option at all when they follow that step.
By the way, my win10 does not display the WD icon in the notification area in the lower right corner at all. Do you think it is not started? Then I checked the process and found that there is no WD process. Do you think it has not started? But it still deletes the files you downloaded! (I installed the third-party anti-virus software and did not delete it. It is obviously WD that is still causing trouble)
Some third-party tools for shutting down WD are not very good at just a shutdown button. After clicking it, it seems to restart, but even after restarting, it is of no use. The WD is still there, and this software only has one button and does not allow you to detect whether the current WD is What state is it, and there is no enable button.
Then some are better done, with current status and on/off buttons, but this software will be deleted by WD first, and I haven't studied whether it is really useful.

If you look at my page, it is completely different from the online tutorials. There is no menu that should be there. How can I continue?
4. Additional information
Sometimes we see Microsoft Defender, what is the difference between it and Windows Defender? To sum it up, there is no difference except the different names.

5. Finally, chrome will also block downloads.
During subsequent use, I found that Chrome also blocks downloads. For example, the prompt is a little different, "Dangerous download content has been blocked." This is a good thing Chrome does. Go to Chrome's Settings->Privacy and Security->Security->Security. You can turn it off by changing it from "Standard protection" to "Unprotected" in browsing.
