You can use the built-in Windows Security app, McAfee, or any preferred <a href=\"https:\/\/www.thewindowsclub.com\/recommended-free-anti-virus-software-for-windows-7\">antivirus software<\/a> to find and remove malware from your PC.<\/li>\n<li>Another thing you should check is whether your web browser is up-to-date or not. If not, <a href=\"https:\/\/www.thewindowsclub.com\/how-to-update-chrome-firefox-edge-opera-browsers\">update your web browser<\/a> and check if the error has stopped.<\/li>\n<li>You can also try <a href=\"https:\/\/www.thewindowsclub.com\/manage-browser-add-ons-windows\">disabling conflicting extensions in your web browser<\/a> and see if it helps.<\/li>\n<\/ul>\n<h4>2] Make sure McAfee WebAdvisor is up-to-date<\/h4>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-439833\" src=\"https:\/\/www.thewindowsclub.com\/wp-content\/uploads\/2023\/10\/update-mcafee-webadvisor.png\" alt=\"\" width=\"700\" height=\"359\" srcset=\"https:\/\/www.thewindowsclub.com\/wp-content\/uploads\/2023\/10\/update-mcafee-webadvisor.png 700w, https:\/\/www.thewindowsclub.com\/wp-content\/uploads\/2023\/10\/update-mcafee-webadvisor-500x256.png 500w, https:\/\/www.thewindowsclub.com\/wp-content\/uploads\/2023\/10\/update-mcafee-webadvisor-300x154.png 300w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<p>You might experience a UiHost.exe Application Error if you are using an outdated version of McAfee WebAdvisor. Hence, make sure you are using the latest version of McAfee WebAdvisor. You can update it using the web browser in which you have installed the extension. Let us see how.<\/p>\n<p>First, open the web browser where you have installed the McAfee WebAdvisor extension. Here, we are taking an example of Microsoft Edge.<\/p>\n<p>Now, click on the <strong>Settings and more<\/strong> (three-dot menu) button and then choose the <strong>Extensions &gt; Manage extensions<\/strong> option.<\/p>\n<p>Next, turn on the <strong>Developer mode<\/strong> toggle and then click on the <strong>Update<\/strong> button.<\/p>\n<p>Once done, restart your computer and check if the UiHost.exe Application Error is fixed now.<\/p>\n<p>Similarly, you can <a href=\"https:\/\/www.thewindowsclub.com\/check-update-browser-plug-ins-extensions-add-ons\">update the McAfee WebAdvisor extension in Chrome and Firefox<\/a> and check if it helps.<\/p>\n<h4>3] Check if the UiHost.exe file is legit<\/h4>\n<p>The error might occur if a virus or malware replaces the genuine UiHost.exe file. Hence, if the scenario is applicable, check if the UiHost.exe file is legit or not. You can do that by checking the digital signature of the file and making sure that it is signed by McAfee. Here are the steps to do that:<\/p>\n<p>First, open the File Explorer using Win+E and then navigate to the following address:<\/p>\n<p style=\"padding-left: 40px;\">C:\\Program Files\\McAfee\\WebAdvisor<\/p>\n<p><strong>Note:<\/strong> If the UiHost.exe file is located at a different location, it is most likely to be a virus; so remove it.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-439832\" src=\"https:\/\/www.thewindowsclub.com\/wp-content\/uploads\/2023\/10\/uihost-file.png\" alt=\"\" width=\"700\" height=\"466\" srcset=\"https:\/\/www.thewindowsclub.com\/wp-content\/uploads\/2023\/10\/uihost-file.png 700w, https:\/\/www.thewindowsclub.com\/wp-content\/uploads\/2023\/10\/uihost-file-500x333.png 500w, https:\/\/www.thewindowsclub.com\/wp-content\/uploads\/2023\/10\/uihost-file-300x200.png 300w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<p>Now, scroll down to the <strong>UiHost.exe<\/strong> file and right-click on it.
