Allow download restrictions

Configures the type of downloads that Google Chrome will completely block, without letting users override the security decision.

If you set this policy, Google Chrome will prevent certain types of downloads, and won't let user bypass the security warnings.

When the 'Block dangerous downloads' option is chosen, all downloads are allowed, except for those that carry Safe Browsing warnings.

When the 'Block potentially dangerous downloads' option is chosen, all downloads allowed, except for those that carry Safe Browsing warnings of potentially dangerous downloads.

When the 'Block all downloads' option is chosen, all downloads are blocked.

When the 'Block malicious downloads' option is chosen, all downloads are allowed, except for those that Safe Browsing assesses to be malware with high confidence. Unlike with dangerous downloads, this does not take into account file type, but does take into account the host.

When this policy is not set, (or the 'No special restrictions' option is chosen), the downloads will go through the usual security restrictions based on Safe Browsing analysis results.

Note that these restrictions apply to downloads triggered from web page content, as well as the 'download link...' context menu option. These restrictions do not apply to the save / download of the currently displayed page, nor does it apply to saving as PDF from the printing options.

See https://developers.google.com/safe-browsing for more info on Safe Browsing.

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
