Chrome Download Says "Failed - Blocked" or "Network Error": How to Fix It

A file won’t finish downloading in Chrome — instead you get “Failed - Blocked”, “Couldn’t download - Network error”, or “Virus detected”.

Why: Chrome blocks or cancels a download for a specific reason: your computer’s security settings, your antivirus, Safe Browsing flagging the file as risky, or the connection dropping mid-transfer. The fix depends on which message you see.

Fix 1: Retry the download the right way

A dropped connection (“Network error” / “Network failed”) often clears on a second try.

1. In the downloads bar or Downloads page (Ctrl+J), click Resume or Retry on the failed item.
2. If that fails, right-click the original download link on the page and choose Save link as…, then pick Desktop or Documents as the destination.
3. Still stuck? Per Google, unwanted software can block downloads — close other apps, restart Chrome, and try once more.

Saving to an everyday folder like Desktop avoids “Insufficient permissions” failures caused by writing to a protected location.

Fix 2: “Download blocked” — security settings stopped it

When Chrome says Download blocked, your computer’s security settings (on Windows, the Attachment Manager) removed the file, not Chrome itself.

1. Confirm you actually trust the file and its source.
2. Check Windows Security and any third-party antivirus for a quarantine or blocked-file notice, and allow the file there if you trust it.
3. Try the download again. If the file is from email or chat, save it to your computer first, then open it.

Fix 3: “Virus detected” / “Virus scan failed”

This message means your virus-scanning software — not Chrome — blocked the file.

1. Open your antivirus and check its logs or quarantine for the file’s name.
2. If you’re certain it’s safe, restore or allow it from within the antivirus, then re-download.
3. If you’re not sure, don’t override it — treat the warning seriously.

Fix 4: Keep a file Chrome itself flagged as risky

If Chrome shows a download warning (dangerous, suspicious, unverified, or insecure), it’s Safe Browsing protecting you. You can still keep the file, but only if you trust it.

1. Open the Downloads page (Ctrl+J) or the downloads tray.
2. Find the warned file and choose Keep (you may need to expand the warning to see the option).
3. For a password-protected archive under Standard protection, enter the file’s password, choose Check for malware, and download only after the scan reports Scan complete.

Google’s guidance: you can always choose to download after a warning, but take download warnings seriously.

FAQ

Why does only one file type fail? Executable and archive types (.exe, .zip, .dll) trigger more checks from Windows and Safe Browsing. A “No file” or “File missing” error instead means the file was moved or deleted on the website — contact the site owner.

The download reaches 100% then says “Failed.” That’s usually the post-download virus scan or security check rejecting it. Check your antivirus logs (Fix 3).
