When you try to download a file using Chrome, you may occasionally get the “Virus scan failed” alert. This means that your browser could not scan the file for malware and blocked the download. Restarting your browser and retrying the download won’t help. Let’s explore what else you can do to get rid of this alert.
How to Fix “Virus Scan Failed” Google Chrome Error
Check Your Browser
Let’s start off by checking your browser. The idea is to make sure that nothing’s interfering with your download.
- Enable Incognito Mode. Try to download the problematic file in Incognito Mode.
- Clear your browser cache. Delete your cookies and cache files, and check if the issue persists.
- Disable all of your extensions. Privacy and security extensions often interfere with the scripts of the websites you’re visiting. They can also limit certain browser functionalities.
- Update your browser. Click on the three-dot menu, go to Help, select About Google Chrome and check for updates.
Use a Different Browser
If the issue persists, switch to a different browser. However, keep in mind that the same error may pop up on other Chromium-based browsers as well. Use Firefox and check if you can download the problematic file.
Check Your Antivirus Log
The “Virus scan failed” alert could also indicate that your antivirus blocked the file download process. Usually, this is because the antivirus has detected something suspicious and blocked the file. If you’re downloading files or programs from third-party download websites, your antivirus may be right. Check the log for details about why the file was blocked in the first place. For step-by-step instructions on how to check the log, go to your antivirus support page.
We don’t recommend turning off your antivirus and firewall to get rid of this error. The file you’re trying to download might be infected with malware. Stay on the safe side, and don’t risk infecting your machine with malware. Hackers can’t wait to turn your machine into a zombie computer.
Disable Attachment Scanning
However, if you are 100 percent sure that the file you’re trying to download is safe, you can skip the attachment scanning phase temporarily. Don’t forget to re-enable the virus scanning option as soon as you’ve downloaded the file.
- Type regedit in the Windows Start Search field and launch the Registry Editor.
- Navigate to
- Note: If the Attachments entry is not available, create it by clicking Policies → New → Key → Attachments.
- Right-click on Attachments, select New, and then DWORD (32-bit).
- Name the new entry ScanWithAntiVirus, and hit Enter.
- Double-click on ScanWithAntiVirus. Change its value to 1, and save the new settings.
- Try to download the problematic file again.
Disable the Windows Attachment Manager
The Attachment Manager’s role is to block unsafe attachments and files. For example, if you’re trying to download suspicious or unsafe files from the Internet, the tool will automatically block and delete them. That could explain why you’re getting the “Virus scan failed” error on Chrome.
You can use the Group Policy Manager to disable the Attachment Manager, although we don’t recommend doing that. Navigate to Group Policy → User Configuration → Administrative Templates → Windows Components → Attachment Manager. As a quick reminder, GPEdit is only available on Windows 10 Pro computers.
If the “Virus scan failed” alert prevents Chrome from downloading files from the Internet, clear your browser cache, and disable your extensions. Make sure you’re running the latest Chrome version on your machine. If the issue persists, use a different browser, and tweak your Registry to disable the attachment scanning option.
