Have you ever encountered a situation where you want to download a file from the Internet, but your browser or your computer blocks it?

In this article, we will show you how to unblock downloads on Chrome and how to unblock downloaded files on Windows. We will also answer some frequently asked questions about this topic.


Why Do You Need to Unblock a Download?




Chrome Blocking Downloads




Google Chrome is one of the most popular web browsers in the world. It has various features that can provide an efficient and safe browsing experience for users. Chrome has done well in terms of browsing security. It can protect you against dangerous websites, downloads, and extensions, which is very useful for those who like making exploration on the Internet.

However, problems may arise when you want to download from an unfamiliar website. Chrome will block certain files that it thinks are unsafe to download, and even stop you from downloading from a certain website. With Chrome blocking downloads, you will be unable to download files even if you know the website is secure.


Windows Blocking Downloads




Even if you can download files from the Internet without any problems, your Windows will also block the files automatically to avoid any potential threats from the unknown files. As a result, you cannot modify or open the files and might receive certain error messages.


The Windows Attachment Manager works by identifying the types of file you download and applying certain security settings to them. Whether or not you receive a warning depends not just on the file type but the type of program you're using and your security settings. Based on this, it will be determined high, moderate, or low risk.

It's worth noting that Attachment Manager makes no judgment on whether a specific file is safe or has malware. Rather, it applies warnings to all files types that fall into the same category regardless of other factors. This is useful so that you can learn which file types are likely to do the most damage and exercise caution accordingly.


Depending on the risk and file type, you may get different warning messages:


  • High risk: Windows found that this file is potentially harmful. To help protect your computer, Windows has blocked access to this file



  • Moderate Risk: The publisher could not be verified. Are you sure you want to run this software?
