<p>Some of the core Windows 10 applications, like Microsoft News that come pre-installed with the operating system are natively displaying ads.</p>

<p>Those ads can sometimes be deceptive and make users believe that their PC is infected with malware or that they have won a prize. Once a fraudulent Ad is picked by the Ad server it is displayed to the user. The advertisement then opens a deceptive web page in the default browser and either open a warning message like &#8220;this PC is infected&#8221; or display a tempting message like &#8220;you have won an iPhone&#8221;. In both cases, inexperienced Windows 10 users might take the bait and get their system infected.</p>
<p>Microsoft MVP volunteer <a href="https://borncity.com/win/2019/06/03/microsoft-windows-10-apps-opens-banner-ads-with-fraudulent-web-pages/" target="_blank" rel="noopener noreferrer">Ingo Böttcher confirmed</a> that Windows Apps may open fake websites and infect Windows 10 machines. According to Böttcher, the problem is caused by fraudulent advertisement campaigns that run on Microsoft&#8217;s advertising network.</p>
<p>Windows 10 users are advised to close the fraudulent web pages. Doing so, no harm will be done to your system.</p>
<p>Experienced users can install a DNS-based ad-blocking software that can deal with the issue while inexperienced Windows users will have to wait for Microsoft to ban fraudulent publishers and ads from their ad network.</p>
<p>Until this is done, please be careful and don&#8217;t be too naive because if something seems too good to be true, it probably isn&#8217;t.</p>
