Description
Setting the policy means users cannot bypass download security decisions. There are many types of download warnings within Chrome, which roughly break down into these categories:
- Malicious, as flagged by the Safe Browsing server.
- Uncommon or unwanted, as flagged by the Safe Browsing server.
- A dangerous file type (e.g., all SWF downloads and many EXE downloads).
Setting the policy blocks different subsets of these, depending on its value:
0 = No special restrictions. Default.
1 = Block malicious downloads and dangerous file types.
2 = Block malicious downloads, uncommon or unwanted downloads, and dangerous file types.
3 = Block all downloads.
4 = Block malicious downloads. Recommended.
