Microsoft is improving Windows Defender with every update for Windows 10 operating system and the company's default antivirus solution is pre-installed on all Windows-powered devices.
- If you have also turned off Windows Update service in Windows 10 and now want to manually update Windows Defender in Windows 10, you will be happy know that manually updating Windows Defender is quite easy. All you need to do is, download Windows Defender updates from Microsoft and then run the update in Windows 10 to update Windows Defender.
- Files you download from the Internet may be blocked due to your computer system's current security settings. In Microsoft Windows, you can manage advanced security settings using the items available in the Control Panel. Web browsers on your computer can be restricted by the security zone level settings located in the Internet Options dialog.
- Hi I just got a new expansion pack for my sims 4 the city living I wanted to play my game and it wouldn't let me and then I started getting fustrated because I tried to run a trouble shoot and and the problem was that my game wasn't compatible with TS4 because my stupid computer blocked the ts4 unau.
If you're looking to install either Windows 10 1903 or Windows 10 1909 (the May 2019 and the November 2019 updates) and you're a user of Avast or AVG Antivirus, you may well find that Microsoft prevents you from updating.
The company has identified a compatibility issue with the antivirus software and is therefore blocking the updates. Microsoft is also advising users not to try to sidestep the block by manually installing the update.

In an update to the documentation detailing known issues with Windows 10, Microsoft explains: 'Microsoft and Avast has identified compatibility issues with some versions of Avast Antivirus and AVG Antivirus. Any application from Avast or AVG that contains Antivirus version 19.5.4444.567 or earlier is affected'.
The company goes on to explain that updates to Windows 10 1903 and Windows 10 1909 for anyone with the problematic software installed.
The fix is very simple: just update Avast or AVG to a newer version, and the updates for Windows will be unblocked. Both Avast and AVG have published support articles about the issue.
Microsoft warns:
We recommend that you do not attempt to manually update using the Update now button or the Media Creation Tool until a new version of your Avast or AVG application has been installed and the Windows 10, version 1903 or Windows 10, version 1909 feature update has been automatically offered to you.

-->Windows Defender Blocking Windows Updates
Applies to:
- Windows 10, version 1703
- Windows 10 Mobile
- Microsoft Edge
Microsoft Defender SmartScreen helps to protect users if they try to visit sites previously reported as phishing or malware websites, or if a user tries to download potentially malicious files.
How users can use Windows Security to set up Microsoft Defender SmartScreen
Windows Defender Blocking Applications
Starting with Windows 10, version 1703, users can use Windows Security to set up Microsoft Defender SmartScreen for an individual device; unless an administrator has used Group Policy or Microsoft Intune to prevent it.
Note
If any of the following settings are managed through Group Policy or mobile device management (MDM) settings, it appears as unavailable to the employee.
To use Windows Security to set up Microsoft Defender SmartScreen on a device
Open the Windows Security app, and then select App & browser control > Reputation-based protection settings.
In the Reputation-based protection screen, choose from the following options:
In the Check apps and files area:
On. Warns users that the apps and files being downloaded from the web are potentially dangerous but allows the action to continue.
Off. Turns off Microsoft Defender SmartScreen, so a user isn't alerted or stopped from downloading potentially malicious apps and files.
In the Microsoft Defender SmartScreen for Microsoft Edge area:
On. Warns users that sites and downloads are potentially dangerous but allows the action to continue while running in Microsoft Edge.
Off. Turns off Microsoft Defender SmartScreen, so a user isn't alerted or stopped from downloading potentially malicious apps and files.
In the Potentially unwanted app blocking area:
On. Turns on both the 'Block apps' and 'Block downloads settings. To learn more, see How Microsoft identifies malware and potentially unwanted applications.
Block apps. This setting will prevent new apps from installing on the device and warn users of apps that are existing on the device.
Block downloads. This setting will alert users and stop the downloads of apps in the Microsoft Edge browser (based on Chromium).
Off. Turns off Potentially unwanted app blocking, so a user isn't alerted or stopped from downloading or installing potentially unwanted apps.
In the Microsoft Defender SmartScreen from Microsoft Store apps area:
On. Warns users that the sites and downloads used by Microsoft Store apps are potentially dangerous but allows the action to continue.
Off. Turns off Microsoft Defender SmartScreen, so a user isn't alerted or stopped from visiting sites or from downloading potentially malicious apps and files.
How Microsoft Defender SmartScreen works when a user tries to run an app
Microsoft Defender SmartScreen checks the reputation of any web-based app the first time it's run from the Internet, checking digital signatures and other factors against a Microsoft-maintained service. If an app has no reputation or is known to be malicious, Microsoft Defender SmartScreen can warn the user or block the app from running entirely, depending on how you've configured the feature to run in your organization.
By default, users can bypass Microsoft Defender SmartScreen protection, letting them run legitimate apps after accepting a warning message prompt. You can also use Group Policy or Microsoft Intune to block your employees from using unrecognized apps, or to entirely turn off Microsoft Defender SmartScreen (not recommended).
How users can report websites as safe or unsafe
Microsoft Defender SmartScreen can be configured to warn users from going to a potentially dangerous site. Users can then choose to report a website as safe from the warning message or as unsafe from within Microsoft Edge and Internet Explorer 11.
To report a website as safe from the warning message
- On the warning screen for the site, click More Information, and then click Report that this site does not contain threats. The site info is sent to the Microsoft feedback site, which provides further instructions.
To report a website as unsafe from Microsoft Edge
- If a site seems potentially dangerous, users can report it to Microsoft by clicking More (...), clicking Send feedback, and then clicking Report unsafe site.
To report a website as unsafe from Internet Explorer 11
- If a site seems potentially dangerous, users can report it to Microsoft by clicking on the Tools menu, clicking Windows Defender SmartScreen, and then clicking Report unsafe website.
