Disabling the smartscreen filter. Disable URL checking. Could it be a virus

To protect data stored on your computer from malicious files and programs in the operating system sis Windows theme integrated Smartscreen filter.

Initially, this function was available only to browser users Internet Explorer, but already from the eighth Windows versions Microsoft made Smartscreen integral part most operating system.

The filter can identify and block previously detected malicious and phishing sites, and allows the user to make informed decisions when downloading files from the Internet.

SmartScreen works in three key areas:

Analyzes website pages when working on the Internet, tracking suspicious ones. If suspicious web pages are detected, the filter issues a corresponding warning to the user;
Checks the sites visited by the user for the presence in the list of previously exposed phishing Internet resources and sites with malicious content. If the requested page is suspicious, the SmartScreen filter blocks access to it for security reasons;
Checks files downloaded by the user according to the list of previously identified sites with malicious and potentially dangerous programs. If the requested file matches a file on the blacklist, SmartScreen reports a security block. If the executable file is already saved on the PC, the filter will warn you about the danger when you try to run it.

Default blue filter Windows screen 10 switched to active mode, but if necessary, you can go into the settings at any time and disable it. The fact is that SmartScreen often mistakenly blocks access to applications that do not pose any threat to the computer.

Please note: if we are talking about a computer running on a network, then in this case only the system administrator has the rights to change this parameter.

What do messages from the Smartscreen filter mean?

When a user tries to run potentially dangerous application or download a malicious file, the system will display a message approximately as follows:

"The Windows Smartscreen filter prevented an unidentified application from running that could put your PC at risk."
"Running the requested program may compromise the security of your computer."
“SmartScreen Filter does not have information about the requested unsigned program. Running it may harm your computer,” etc.

If a program or file really raises security concerns, then it is better to refrain from downloading and/or running it.

However, very often a smartscreen filter ends up blocking a known safe application or web page.

It also happens that while working in Explorer on a computer with Windows 10, a notification suddenly pops up on the screen, which notifies that “the Windows smartscreen filter is currently unavailable, so it cannot determine whether it is safe to run this application.” The last message is displayed with a link to the lack of Internet connection.

Protecting Personal Computer from viruses and other dubious files, SmartScreen becomes a real problem for users of the latest versions of Windows. The only way to get rid of it is to deactivate the filter. It couldn't be easier to do this.

The Windows 10 Store also interacts with the SmartScreen filter, since the service analyzes the addresses of all products installed from this resource. This means that here too SmartScreen can become an obstacle to downloading any program or game.

To deactivate the filter, simply perform the following steps:

Click the “Start” button;
Go to “Options”, select “ Confidentiality«;
In the “General” section, in the sub-item regarding the SmartScreen service, move the switch to the “Off” position.

VIDEO INSTRUCTION

To disable smartscreen filter on Windows 8.1, you should perform the following steps sequentially:

Look at the Windows Action Center through the Control Panel;
In the left menu select the tab " Change Windows SmartScreen settings«;
In the dialog box that appears, “ What do you want to do with unidentified applications?"check the box next to" Do nothing (Disable Windows Smartscreen), confirm the selection by pressing the OK button;

The SmartScreen function is a special algorithm for protecting your computer from malicious code. Before launching an application, this tool checks it using built-in algorithms and, if unsuccessful, simply blocks the program from launching. Applications that do not have a signature are especially often blocked.

Of course, to run untrusted programs on the system that have not passed verification, it is better to disable filtering altogether so as not to encounter constant blocking. Since the defender has been integrated into the system since Windows 8, it should be disabled at the same level - using special sections of the system.

It is important to understand that when turning off this system protection, you yourself reduce the system’s likelihood of resisting viruses. This makes the computer more vulnerable. It is better to consider alternative options for installing software, for example: you can probably find an original program or there is a similar one in functionality that does not require disabling filtering.

Also, if you have installed third party antivirus, which performs the same task, then you can and even should disable native filtering so that there are no application conflicts.

We will look at how to disable the SmartScreen filter in Windows 10 at different levels: browser, application scan and system protection, in more detail below.

Disable SmartScreen via Control Panel

You can deactivate such a function using 2 options: from the control panel or in the policy editor. Both methods are easy to use and only require strict adherence to the instructions.

To deactivate SmartScreen using the Control Panel you need:

Click on Start and “Control Panel”;
Find the "Security and Maintenance" tile;

On the left side of the window you will see “Change Windows SmartScreen settings”;
When you call up the “What do you want to do...” window, you should check the box next to the last item, “Do nothing.”

By completing these steps, you take away the authority from SmartScreen and full responsibility for the health of the system passes to you.

There are some situations in which these filter settings items are not active; they are highlighted in gray and their position cannot be changed. This problem is resolved with:

Win + R and regedit;
Go to the path HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System;
The "EnableSmartScreen" setting must be removed.

An alternative method is through group policies

Another option that achieves the same goal is to disable SmartScreen using Group Policy. It is worth mentioning that the method works for Windows 10 professional and corporate. IN home version This option is not provided to users.

Press Win + R and paste gpedit.msc;
Now in the “Computer Configuration” column, select “Administrative Templates”;
From the list, select " Windows components»;
Now find "Explorer";
Among the options on the right edge will be “Customize Windows SmartScreen”;

Set the parameter to “Enabled” and at the bottom of the window “Disable SmartScreen”.

Both methods help to achieve the same result only using different methods.

In fact, we did not completely disable filtering on the computer, but only when launching applications. SmartScreen is still active in checking application connections and in the Edge browser.

Disable URL checking

Program installation or update functions may not work completely or may produce errors when filtering in this way. Since if SmartScreen detects a source as not benign, it will be blocked and the application will lose access to the network; this is vital for some programs. This filtering algorithm can also be disabled:

Win + I and go to “Privacy”;
Among the options in the “General” tab is “Enable SmartScreen filter...”;
Set the slider to Off.

Thus, SmartScreen's influence will be limited to the browser, where it will still help Microsoft Edge in work and safety. If this does not suit you, you can also disable this functionality.

Disable SmartScreen in the Edge browser

The necessary steps to disable it must be performed in the browser itself.

LMB on the Microsoft Edge menu button (upper right corner);
Now at the end of the list, click on “Advanced options”;
After that, scroll further, at the very end “Helps protect your computer...” set the value to “Off.”

After disabling SmartScreen at all levels, it becomes completely inactive and you will no longer receive unpleasant messages about blocked applications and their connections.

The speed of completing tasks increases significantly when filtering is turned off, but this is all at the expense of privacy. Based on your preferences, you can set your security level.
