Windows 10 proactively scans for and stops threats to your system. It does this by scanning downloaded files or running apps. If you have browser control enabled in Windows Defender, malicious files you download will be scanned and blocked before you can even view them.
Windows 10 will scan a file when it is downloaded and copied, but the SmartScreen will also check to see if it is signed or not when you try to run it. This usually happens for executable or removable files.
Fix SmartScreen is currently unreachable
SmartScreen scans files as you open / run them. Windows Defender will already have checked the downloaded file, but at least a second scan will be performed.
To view the file, SmartScreen scans for known signs of malicious files. These signals are constantly updated to ensure that new threats are prevented. If you try to open / run an app, and find that you can’t reach “SmartScreen error now”, here’s what you can do.
Check internet connection
SmartScreen works if you have an internet connection. Without an active internet connection, it will not see the updated list of malicious file tokens.
- Click on the WiFi image in the system tray.
- look for your network in the panel.
- He should say ‘Connected, secure’ no ‘Connected, Internet’ below. If it does not, you do not have access to the internet.
Check the status of SmartScreen service
SmartScreen is a service; it runs on the desktop but requires communication with an online server to operate. If the server is down, you will see a “SmartScreen currently unreachable” error if your internet is working.
Unfortunately, there is no status page for the service. You must check online forums, and various Microsoft Twitter accounts to find out if the service is down.
Build up SmartScreen
SmartScreen can be problematic and can turn off Off and On the repair.
- Open Windows Defender.
- go to App and browser control.
- Click Reputation-based protection settings.
- Turn the Disable “Check apps and files”.
- Restart the system.
- Return to Windows Defender and turn on the Reset “View apps and files”.
- Open the file and SmartScreen scans it.
Turn off proxies and VPN
A proxy or VPN should not block the SmartScreen but there are always exceptions. If you have configured a proxy on Windows 10, or are using a VPN, turn them off and try opening the file.
Scan for VirusTotal
If the SmartScreen still doesn’t work, you can try scanning the file with VirusTotal even though it only works for exectuables.
- Visit him VirustTotal.
- Click Select File.
- Upload file.
- Once the original results are displayed, click the update button arrow on VirusTotal to run a new scan.
- If the the file is safe, bypass SmartScreen and open it.
SmartScreen is conservative when it comes to file blocking. It will block anything for seemingly harmless reasons.
While this is a good thing in general ie, you want your anti-virus to be too careful, sometimes it is not ignored. If you know the file is safe, skip SmartScreen.
- Double-click the file you want to run.
- On the “Currently unreachable SmartScreen” screen, click Run Anyway.
- The will open a file.
Long-term problems with SmartScreen are rare. If the service has never worked since you installed Windows 10 or stopped working after an update, you may need to revert the update, wait for a patch update, or consider it. Create a new user.
