Unfortunately, users reported the This unsafe download was blocked by SmartScreen message while downloading certain files, and today we’re going to show you how to fix it on Windows 10.

How do I bypass the Microsoft SmartScreen filter on Windows 10? The simplest way is the ‘Download unsafe file’ option. This only applies if you’re absolutely certain that the file is safe and the message is the result of an error.

A more complicated solution that will surely work is to disable the SmartScreen.

If you want to know how to do that, keep on reading.

Quick Tip:

If you need a browser that will keep you safe from pretty much anything, then look no further than Opera.

This Chromium-based Internet browser is fast and efficient, and it comes with a plethora of free security tools that no other web browser has.

For example, you get a free VPN that haw no traffic quota, an ad-blocker that will prevent any ad-ware from spamming you, and a tracker-blocker so anything you do while using Opera remains unrecorded.

With so many layers of protection, having to deal with unsafe downloads will be a thing of the past as soon as possible.



Not just a web browser, but also a VPN, and ad-blocker and a tracker-blocker, all rolled up into one amazing tool.
