What was a criticism last year may be a moot point in 2018. Check out this video to see the results:<\/p>\n<p><iframe loading=\"lazy\" width=\"840\" height=\"473\" src=\"https:\/\/www.youtube.com\/embed\/tFiw8JQxyO4?feature=oembed\" frameborder=\"0\" allow=\"autoplay; encrypted-media\" allowfullscreen><\/iframe><\/p>\n<h3>How does Windows Defender detect and stop threats?<\/h3>\n<p>It&#8217;s important to understand what Defender does in order to compare it to other products on the market. Windows Defender uses basic signature-matching scanning to compare unknown files with its database of known threats. Essentially, it&#8217;s checking the file in question against a catalog of viruses. Defender also uses heuristic analysis, which monitors software behavior to catch malware or malware that rapidly changes its code to dodge detection.<\/p>\n<p>It lacks the bells and whistles of Avast, Bitdefender, or Norton, but it is a semi-effective line of defense nonetheless.<\/p>\n<h3>Windows Defender Security Center<\/h3>\n<p>&#8220;Windows 10 respects your freedom to choose AV products of your choice,&#8221; says Rob Lefferts, Partner Director of Windows &amp; Devices Group. In <a href=\"https:\/\/blogs.windows.com\/windowsexperience\/2017\/01\/23\/introducing-windows-defender-security-center\/\" target=\"_blank\" rel=\"noopener noreferrer\">this article<\/a>, Lefferts accepts that people will frequently opt to forego Defender in order to use other software, and, in fact,\u00a0<strong>encourages<\/strong> users to seek the &#8220;protection software and services that they like best.&#8221;<\/p>\n<p>As of January 2017, the Windows Defender Security Center was introduced, bringing in new security features and controls. This included firewall and network protection, device performance and health, app and browser control, family options, and of course protection against viruses and threats.<\/p>\n<p><iframe loading=\"lazy\" width=\"840\" height=\"473\" src=\"https:\/\/www.youtube.com\/embed\/QE-3zbvtdKI?feature=oembed\" frameborder=\"0\" allow=\"autoplay; encrypted-media\" allowfullscreen><\/iframe><\/p>\n<h3>The final consensus<\/h3>\n<p>Defender is steadily growing into a more reliable means for data protection, but it&#8217;s not there yet. Defender still has a long way to go before it can go toe-to-toe with powerful names like Bitdefender, Norton, or Kaspersky.<\/p>\n<p>That said, considering that Defender is a relatively lightweight program that you get by default with Windows 10, you&#8217;re actually getting a pretty decent product. We recommend pairing it with something else for double the safety, such as Bitdefender. Set Windows Defender to run a scheduled quick scan every now and again, then do a full test with Bitdefender when you&#8217;ve got the time and processing power to spare.<\/p>\n<!-- Shortcode [playwire] does not match the conditions -->\n<div class=\"sc-related-articles-white\">\r\n<p class=\"sc-related-articles-white__title\">More from Softonic<\/p>\r\n  <div class=\"sc-related-articles-white__row\">\r\n    <a title=\"What is Windows 10 Ultimate Performance mode?\" href=\"https:\/\/en.softonic.com\/articles\/what-is-windows-10-ultimate-performance-mode\">\r\n    <div class=\"sc-related-articles-white__article\">\r\n      <div class=\"sc-related-articles-white__image\">\r\n        <div style=\"background-image:url(https:\/\/articles-img.sftcdn.net\/sft\/articles\/auto-mapping-folder\/sites\/3\/2016\/01\/cover.jpg)\"><\/div>\r\n      <\/div>\r\n      <div class=\"sc-related-articles-white__text\">\r\n        <p>What is Windows 10 Ultimate Performance mode?<\/p>\r\n      <\/div>\r\n    <\/div>\r\n    <\/a>\r\n    <a title=\"How to make Windows 10 run faster in 9 easy steps\" href=\"https:\/\/en.softonic.com\/articles\/how-to-make-windows-10-run-faster-in-9-easy-steps\">\r\n    <div class=\"sc-related-articles-white__article\">\r\n      <div class=\"sc-related-articles-white__image\">\r\n        <div style=\"background-image:url(https:\/\/articles-img.sftcdn.net\/sft\/articles\/auto-mapping-folder\/sites\/3\/2018\/03\/how_to_w10_image7.jpg)\"><\/div>\r\n      <\/div>\r\n      <div class=\"sc-related-articles-white__text\">\r\n        <p>How to make Windows 10 run faster in 9 easy steps<\/p>\r\n      <\/div>\r\n    <\/div>\r\n    <\/a>\r\n  <\/div>\r\n  <div class=\"sc-related-articles-white__row\">\r\n    <a title=\" The best 9 Windows 10 productivity tips and tricks\" href=\"https:\/\/en.softonic.com\/articles\/the-best-9-windows-10-productivity-tips-and-tricks\">\r\n    <div class=\"sc-related-articles-white__article\">\r\n      <div class=\"sc-related-articles-white__image\">\r\n        <div style=\"background-image:url(https:\/\/articles-img.sftcdn.net\/sft\/articles\/auto-mapping-folder\/sites\/3\/2018\/03\/w10_Productivity_image3.png)\"><\/div>\r\n      <\/div>\r\n      <div class=\"sc-related-articles-white__text\">\r\n        <p> The best 9 Windows 10 productivity tips and tricks<\/p>\r\n      <\/div>\r\n    <\/div>\r\n    <\/a>\r\n    <a title=\"3 ways to secure Windows 10\" href=\"https:\/\/en.softonic.com\/articles\/3-ways-to-secure-windows-10\">\r\n    <div class=\"sc-related-articles-white__article\">\r\n      <div class=\"sc-related-articles-white__image\">\r\n        <div style=\"background-image:url(https:\/\/articles-img.sftcdn.net\/sft\/articles\/auto-mapping-folder\/sites\/3\/2018\/03\/windows-hello.png)\"><\/div>\r\n      <\/div>\r\n      <div class=\"sc-related-articles-white__text\">\r\n        <p>3 ways to secure Windows 10<\/p>\r\n      <\/div>\r\n    <\/div>\r\n    <\/a>\r\n  <\/div>\r\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>As malware evolves to be more malicious by the day, so too must the anti-malware tools we use to fight back and keep our data safe.
