It is still around in 2026, now as <strong>Trellix Stinger<\/strong>, after McAfee&#8217;s enterprise business became Trellix. Here is how to download McAfee Stinger, what it can and cannot do, and how to use it to clean an infected Windows PC.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-30163\" src=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/mcafee-stinger.png\" alt=\"McAfee Stinger antivirus tool scanning a PC\" width=\"500\" height=\"398\" srcset=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/mcafee-stinger.png 500w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/mcafee-stinger-150x119.png 150w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/mcafee-stinger-300x238.png 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/p>\n<p><strong>Quick answer:<\/strong> McAfee Stinger, now Trellix Stinger, is a free portable virus scanner for Windows that finds and removes specific common threats. Download the latest copy from the Trellix free tools page, run it without installing, and scan.

It does not install, does not run in the background and does not conflict with your existing antivirus. It targets a defined list of prevalent malware families and uses the same scan engine technology as Trellix&#8217;s commercial products, including process scanning and digitally signed definition files. Because it is portable, you can run it from a USB drive on a PC that is too infected to install normal security software.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"McAfee_Stinger_vs_Trellix_Stinger\"><\/span>McAfee Stinger vs Trellix Stinger<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In 2021 McAfee sold its enterprise business, which was merged with FireEye and renamed <a href=\"https:\/\/www.trellix.com\/\" target=\"_blank\" rel=\"noopener\">Trellix<\/a>. Stinger moved with it, so new versions carry the Trellix name. The consumer company, <a href=\"https:\/\/www.mcafee.com\/\" target=\"_blank\" rel=\"noopener\">McAfee<\/a>, continues to sell McAfee Total Protection separately. Old McAfee download links for Stinger no longer work.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_download_and_use_Trellix_Stinger\"><\/span>How to download and use Trellix Stinger<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ol>\n<li>Open the <a href=\"https:\/\/www.trellix.com\/downloads\/free-tools\/\" target=\"_blank\" rel=\"noopener\">Trellix free tools page<\/a> and download Stinger (64-bit for most PCs, 32-bit for older systems).<\/li>\n<li>Always download a fresh copy before each use. Stinger has no update feature; each release includes the latest definitions.<\/li>\n<li>Right-click the file and choose <strong>Run as administrator<\/strong>.<\/li>\n<li>Click <strong>Customize my scan<\/strong> to add drives or folders, or keep the default which scans running processes, memory and common locations.<\/li>\n<li>Click <strong>Scan<\/strong>. Stinger repairs infected files by default and keeps backups in its quarantine folder.<\/li>\n<li>Read the log when it finishes, restart the PC, and run a full scan with your regular antivirus.<\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"What_Stinger_cannot_do\"><\/span>What Stinger cannot do<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>It does <strong>not provide real-time protection<\/strong>, so it will not stop new infections.<\/li>\n<li>It detects a <strong>limited set<\/strong> of threats, not everything a full antivirus finds.<\/li>\n<li>It works on <strong>Windows only<\/strong>, not Mac, Android or iPhone.<\/li>\n<\/ul>\n<p>For everyday protection, keep Microsoft Defender or a full security suite running.

Copy the latest Stinger file to a USB drive from a clean computer, plug it in, and run it straight from the drive. It is also handy for IT support staff who clean many PCs, because nothing needs to be installed or uninstalled afterwards.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"FAQ\"><\/span>FAQ<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Is_McAfee_Stinger_free\"><\/span>Is McAfee Stinger free?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Yes.
