The right remedy to solve the problem of Windows 10 can not download files

In daily operation, some users find that when they use the browser to download files or save attachments in emails, sometimes the system will pop up messages such as “Security Alert” or “Virus Detected”, so the download cannot be completed (Figure 1). This problem may be caused by the browser’s download settings or blocked by the “Attachment Manager” that comes with Windows 10. If you have encountered similar problems, you can try the following methods to solve them.

Note: For security reasons, only important files or emails, in an absolutely secure environment, such as a virtual machine, or when you can absolutely confirm that a false alarm was generated, should be downloaded with the anti-virus capability turned off.

Let’s first check the browser settings to make sure it is set to allow file downloads. Type “inetcpl.cpl” in the search box, and click “Security→Ineternet→Custom Level” in the “Internet Properties” window that opens. “. Then in the pop-up “Security Settings” window, find “Download → File Download” and set it to “Enable”. Continue to find the “Other → Load applications and unsafe files” option and set it to “Prompt (recommended)” (Figure 2).

If the system still prompts that the file cannot be downloaded, such as pop-up messages like “virus detected”, then you need to turn off the protection function of Windows 10 “Attachment Manager”.

Start the Registry Editor, expand [HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesAttachments] in turn (if there is no “Attachments If there is no “Attachments”, create a new one), right-click in the right pane and select “New → DWORD (32-bit) Value”, name it “ScanWithAntiVirus”, and set the “Value Data” to “ScanWithAntiVirus”. “Value Data” is set to “1” (Figure 3).

Finally, if you restart your computer and download again, you will usually be fine. It is important to note that the act of downloading itself does tend to trigger false alarms, but when an alarm occurs, the file itself is still very likely to have problems, so after downloading the file you should still change the above key value to “3” and let the system enable the virus scan function to scan the file, and never open it if it alarms again.

Users using Windows 10 Professional can also turn off download protection via Group Policy. Launch Group Policy Editor, expand “User Configuration → Administrative Templates → Windows Components → Attachment Manager”, double-click “Do not keep regional information in file attachments” in the right pane, and click “Enabled ” can be. After downloading the file and then reset it to “not configured”, you can restore the default security settings (Figure 4).
