How To Fix Google Chrome Download "Virus Scan Failed" Error.

Google Chrome is one of the fastest browsers to surf the internet and download stuff online; sometimes, you may get an error when you try to download anything from the web that is “Failed- Virus Scan Failed.”

This error occurs when Google Chrome can’t check for the security certificate of the downloaded files from their publisher and Chrome just can’t scan the program or file.

This happens due to malware in your computer, which may be a virus, adware, or browser hijacker. Or there may be some conflicting programs.

Sometimes, when you uninstall a program, its registry entries remain active. If you uninstalled an antivirus like McAfee, there is a high chance of a download fail error since the antivirus overtakes Chrome to scan downloaded items.

This is annoying when you download any antivirus to scan your computer, but you can’t download the antivirus itself.

This will apply to all major versions of Windows, including Windows 11/10 and older.

After that, we will fix the root cause and revert the changes. Follow the below steps –
