Change the security settings on your computer

Your computer may be set to block downloads completely. Check your Windows Internet security settings to ensure you’re able to download files:

Changing these settings will affect Google Chrome as well as other Internet browsers on your computer.

  1. Go to the Start menu > Control Panel.
  2. Select Internet Options. This should open the Internet Properties window.
  3. Select the Security tab.
  4. Select Internet zone (globe icon).
  5. Click the Customise level button. This will open the Security Settings window.
  6. Scroll down to Downloads > File download.
  7. Select Enable.
  8. Scroll down the list further to Miscellaneous > Launching applications and unsafe files.
  9. Select Prompt.
  10. Click OK.

If you are downloading a file from a website that belongs to a different security zone other than Internet, you should check the security settings for that zone. Some Internet settings, including Security Zone settings, are managed by your system administrator. Learn more about how to use security zones

Possible causes of error message: Virus Scan Failed

Here are a few reasons why you might see the message above:

  • Malware: If your computer is infected with malware it may cause your download to fail.
  • Malfunctioning antivirus software: Some antivirus programmes support on-access scanning of files. If you have on-access scanning and it is enabled, try disabling download scanning temporarily until you resolve the issue with your antivirus software. 

To disable attachment scanning, read the “Notify antivirus programmes when you open attachments” section from Microsoft's article on how the Attachment Manager works

  • Corrupted registry settings: If any required registry settings are missing or corrupt, the virus scan will fail. In this case, disabling download scanning as mentioned in the previous section will not help. 

Follow the instructions below to restore missing registry keys: 

These steps involve making changes to the Windows registry on your computer. Editing the Windows registry is an advanced process, so you might want to contact your system administrator for help.

  1. Enter the keyboard shortcut Windows key +E to open Windows Explorer.
  2. In the Windows Explorer window that appears enter the following in the address bar: cmd.exe
  3. In the command prompt window that opens, type the following: regsvr32 urlmon.dll
