Existe algum sinalizador para desativar os downloads?

Como desativar o download no Google Chrome?

Prevent users from downloading files

Supported on Chrome 61 and later.

As an administrator, you can specify whether users can download files from the Internet using Google Chrome. For example, you might want to let users download files but block any that are dangerous, such as malware. If users try to download dangerous files, Google Safe Browsing shows them a security warning that they can’t bypass.

Apply policy to users

To apply restrictions to downloads, configure the DownloadRestrictions policy.

You can restrict downloads that are triggered on webpages when users click a download link on the page, or right-click a file and choose Save link as....

Restrictions don’t apply when users save the currently displayed webpage. To save a webpage, users can:

• Click File and then Save Page as…, or
• Click Print and choose Save as PDF for the destination.

Download restriction options

You can specify the type of downloads that Google Chrome will block, depending on how secure they are.

• 0 (No special restrictions) — Downloads go through the usual security restrictions based on Safe Browsing analysis results.
• 1 (Block dangerous downloads) — Downloads are allowed, except for those that carry Safe Browsing warnings.
• 2 (Block potentially dangerous downloads) — Downloads are allowed, except for those that carry Safe Browsing warnings of potentially dangerous downloads.
• 3 (Block all downloads) — All downloads are blocked.
