Download errors & warnings

You might see an error message when a download fails. It will show up on the download bar at the bottom of your browser screen or in the a download page that opens. If something you’re about to download could cause problems, Chrome also warns you.

Common warnings for harmful or unwanted programs

Certain downloads can cause viruses, leak your private data, change your browser and computer settings, or add unwanted extensions or toolbars to your browser. Chrome warns you of potential issues:

  • Malicious download warning: You tried downloading malware.
  • Uncommon download warning: You tried downloading an unfamiliar and potentially dangerous piece of software. You should only download programs from sites you trust.
  • Unwanted software download warning: You tried downloading a deceptive piece of software. This program, disguised as a helpful download, may actually make unexpected changes to your computer.
  • Virus detected: Antivirus software detected a virus. Your downloaded file may have a virus and, as a result, the file you attempted to download was removed by the Windows Attachment Manager.

Download errors and how to fix them

Blocked download message

If you see a message that says that your download was blocked, that means that security settings on your computer blocked the file. Find out how to adjust Chrome browser security settings.

Windows users: The file you attempted to download was removed by the Windows Attachment Manager. Check your Windows Internet security settings to see which types of files you’re able to download and why that file was blocked.

If you’re still having problems, you can find more information in the Google Chrome Help Forum.

Virus scan failed message

Sometimes your virus scanning software will block you from downloading a file or program. If you see the “virus scan failed” message, you can check your virus scanning software for more details about why that file was blocked.

Windows users: The file you attempted to download was removed by the Windows Attachment Manager. Check your Windows Internet security settings to see which types of files you’re able to download and why that file was blocked.

Insufficient permissions and download errors

If you receive a message saying that you don’t have the right permissions to download a file or program or you receive a network or download error message, you can close out of the installation and try again later.

Some of the common messages you might see are:

  • Insufficient permissions: Can’t save due to insufficient permissions.
    You may not have the necessary permissions or some other application, typically antivirus software, was accessing the downloaded file at the same time as Google Chrome. Try to download the file again or save it to another location.
  • Network error: Unknown network error. There was a problem with the network during the download.
  • Download error: There was a problem during the download.

If you’re still having problems, you can find more information in the Google Chrome Help Forum.

File not found and server problems

If you see a message that says that there was no file or that there was a server problem, contact the server administrator.

NETWORK_FAILED message

If you see an error message that says “NETWORK_FAILED” when you try to install an app, extension, or theme from Chrome Web Store on Windows, it’s possible that third-party software on your machine is blocking the installation.

First, remove the third-party software

  1. Install a reputable malware-fighting tool. You can find a recommended one in our Safety Center.
  2. Download and run the Software Removal Tool. This Google tool removes software known to affect Chrome.

Then, try to install the app, extension, or theme again

Go to Chrome Web Store and try to install the app, extension, or theme that failed earlier.

If you still can't install the app, extension, or theme, re-install Chrome

  1. Uninstall Chrome.
  2. Re-install Chrome.

If you’re still having problems, you can find more information in the Google Chrome Help Forum.

Turn off phishing and malware warnings

If you don't want Chrome to show you download warnings, you can turn off your phishing and malware protection setting. Turning off these warnings will also turn off other malware and phishing alerts:

  1. In the top-right corner of the browser window, click the Chrome menu Chrome menu.
  2. Select Settings.
  3. Click Show advanced settings.
  4. Under "Privacy," uncheck Enable phishing and malware protection.

Software developers: To help protect users, Google maintains a list of websites that are known to host malicious downloads and a list of trusted software publishers. If you're a software publisher and your binaries are flagged by Chrome, learn how to resolve malware or unwanted software issues related to your downloads.
