That is confirmed by a quote from Microsoft&#8217;s web site:<!--more--><\/p>\n<blockquote><p>SmartScreen checks files that you download from the web against a list of reported malicious software sites and programs known to be unsafe. If it finds a match, SmartScreen will warn you that the download has been blocked for your safety. SmartScreen also checks the files that you download against a list of files that are <span style=\"color: #8a0023;\"><strong>well known and downloaded by many people who use Internet Explorer<\/strong><\/span>. If the file that you\u2019re downloading isn\u2019t on that list, SmartScreen will warn you. (Source of this quote: <a href=\"https:\/\/support.microsoft.com\/en-us\/help\/17443\/microsoft-edge-smartscreen-faq\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/support.microsoft.com\/en-us\/help\/17443\/microsoft-edge-smartscreen-faq)<\/a><\/p><\/blockquote>\n<p>As you can understand this makes absolutely NO SENSE as people who use EDGE and Internet Explorer are just 4% so it can not be &#8220;downloaded by many people who use Internet Explorer&#8221; &#8211; see the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Usage_share_of_web_browsers\" target=\"_blank\" rel=\"noopener noreferrer\">usage shares of all browsers<\/a> as of 13.02.2020 as listed on Wikipedia:<\/p>\n<p><a href=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/Browsers.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1281 size-full\" src=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/Browsers.png\" alt=\"Web Browser Usage\" width=\"579\" height=\"376\" srcset=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/Browsers.png 579w, https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/Browsers-300x195.png 300w\" sizes=\"auto, (max-width: 579px) 100vw, 579px\" \/><\/a>So if we release a new version, Microsoft will display that warning until ALL our users download that version as most likely even fewer than 4% of them are using IE or EDGE. So it turns out that such a message is there just to scare users. We will clarify that in detail as there is a very good reason for Microsoft to do that. In addition, Smartscreen is spying on you by logging what you install on your machine.<\/p>\n<h2>Why does Windows SmartScreen display red Warning Messages?<\/h2>\n<p>Microsoft and the so-called &#8220;antivirus&#8221; vendors are working in partnership with companies that issue code-signing certificates. Those certificates cost thousands of dollars yearly. Like that was not enough, they recently introduced a new type of EV certificate that even cost tens of thousands of dollars yearly. Those certifications on the other hand are totally useless &#8211; read why in the next section.<\/p>\n<p>So the software vendors are pushed to pay those subscriptions in order to get rid of such warnings. In a very obvious translation &#8211; &#8220;Pay the ransom or we will scare your users&#8221;. That is not something that we like or approve. That is something that can only harm the Internet and the IT world. Though we can decide to pay that &#8220;ransom&#8221; what will happen with the developers that create free tools or the open-source organizations that can not afford to pay such fees? It is clear &#8211; they will be &#8220;killed&#8221; as their users will be scared by such nonsense warnings. We do not approve such a monopoly and we do not intend to sponsor it. We have already covered a similar topic in our <a href=\"https:\/\/www.mindgems.com\/article\/f-secure-review-worst-and-unreliable-antivirus-tool-incorrect-scan-results-stay-away\/\" target=\"_blank\" rel=\"noopener noreferrer\">Worst Antivirus Tools<\/a> article.<\/p>\n<p>Another reason for those messages is the attempt of Microsoft to copy the Apple Store by providing a <a href=\"https:\/\/www.microsoft.com\/en-us\/store\/apps\/windows\" target=\"_blank\" rel=\"noopener noreferrer\">Microsoft Store<\/a> which is not doing well enough. Scaring the users with red warning messages on independent vendor websites aims to push them towards the MS Store. This will provide Microsoft extra profit both from vendors and users.<\/p>\n<h2>Why Software Code-signing Certificates are a Gimmick<\/h2>\n<p>The only purpose those certificates serve is to prove that the file that you receive is coming unmodified in the form provided by the vendor. So the only way such a certificate can be useful is if you have downloaded a file from a third-party unknown website.<\/p>\n<p>If you value your security you should download from the vendor websites rather than from third-party locations. If you download a file from our website &#8211; your connection to us is over a secure SSL connection and you can be 100% sure that the file is unmodified and is provided by us. Therefore, it is absolutely irrelevant if the file was signed or not. That signature has meaning only if you are downloading our files from third parties.<\/p>\n<h2>How To Test A File For Malicious Content Without Downloading It?<\/h2>\n<p>If you have doubts, you can upload or paste a link to a file at VIRUSTOTAL DOT COM to scan it. It will scan a file with 60+ antivirus tools simultaneously. You do not even need to download the file &#8211; just copy its download URL. Of course, there are poor tools that may report false positives (incorrect detection as a threat) there too. Nevertheless, if you see that 65 out of 67 antivirus tools report a file as SAFE you can be sure that it is.<\/p>\n<h2>How To Disable Windows Smartscreen?<\/h2>\n<p>The best thing to do is to stop using IE or EDGE completely.\u00a0 96% of the world can not be wrong that those browsers are not good. You can also disable Windows Smart Screen as it is useless or just ignore its nonsense as displayed below.<\/p>\n<blockquote><p>To turn SmartScreen on or off in the new Microsoft Edge:<\/p>\n<p>Select Settings and more &gt; Settings &gt; Privacy &amp; services .<br \/>\nScroll down to Services, and turn Microsoft Defender SmartScreen on or off.<\/p><\/blockquote>\n<h2>How To Override Windows Smartscreen Warnings In Internet Explorer?<\/h2>\n<p>If you insist on using them (IE and EDGE), once you save your file, click on &#8220;Actions&#8221; then &#8220;More options&#8221; and choose &#8220;Run anyway&#8221; &#8211; see the screenshots below.<\/p>\n<p><a href=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/IE1.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-1282 size-full\" src=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/IE1.png\" alt=\"Windows Smart Screen Downloads Blocked\" width=\"664\" height=\"511\" srcset=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/IE1.png 664w, https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/IE1-300x231.png 300w, https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/IE1-624x480.png 624w\" sizes=\"auto, (max-width: 664px) 100vw, 664px\" \/><\/a><a href=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/IE2.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1283 size-full\" src=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/IE2.png\" alt=\"Windows Smart Screen Warning\" width=\"500\" height=\"448\" srcset=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/IE2.png 500w, https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/IE2-300x269.png 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<h2>How To Override Windows Smartscreen Warnings In Microsoft Edge?<\/h2>\n<p>The latest Microsoft Edge is even more aggressive than Internet Explorer.<br \/>\nFollow the steps below to get rid of that nonsense warning.<\/p>\n<ol>\n<li>Click the three dots near the downloaded file<\/li>\n<li>Report this file as safe to Microsoft<\/li>\n<li>Click Keep<\/li>\n<\/ol>\n<p><a href=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/EdgeDownload.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1360\" src=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/EdgeDownload.png\" alt=\"Edge Download Warning\" width=\"514\" height=\"148\" srcset=\"https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/EdgeDownload.png 514w, https:\/\/www.mindgems.com\/article\/wp-content\/uploads\/2020\/02\/EdgeDownload-300x86.png 300w\" sizes=\"auto, (max-width: 514px) 100vw, 514px\" \/><\/a>Unfortunately, Edge is even more annoying than Internet Explorer and will ask the same thing even if you have already clicked KEEP.
