Article: You can do this by visiting https://www.microsoft.com/en-us/download/malicious-software-removal-tool-details.aspx in a browser.  Use this method if you are unable to run a scan or update your anti-malware tool. You can also use this method if your usual anti-malware tool failed to fix the issue. If you can't use a web browser or connect to the internet on the infected PC, download the tool to a working computer, follow the download steps on a working computer. You can then copy or burn the tool to removable media and insert that into the infected PC. It's the red button near the center of the page. If you see a screen that displays recommended downloads, remove the check marks from each download, then click No thanks and continue to DirectX End-User Runtime Web Installer at the bottom-right corner. Select the Downloads folder if not already selected, and then click Save to start the download. If you are downloading the tool on a different computer because you aren't able to do so on the infected one:   USB drive: Connect the drive to the PC, then copy the tool (the file that begins with "Windows-kb" and ends with ".exe") to it from the Downloads folder.  CD/DVD-ROM: If the infected computer has a CD/DVD-ROM drive, you can burn the tool to a disc instead. It starts with "Windows-KB" and ends with ".exe." You'll typically have to click Yes to verify that you want to run the tool. If the malware prevents you from running the tool, you'll need to run the tool in Safe Mode. Follow these steps to reboot into Safe Mode, then try again:  Click the Start {"smallUrl":"https:\/\/www.wikihow.com\/images\/0\/07\/Windowsstart.png","bigUrl":"\/images\/thumb\/0\/07\/Windowsstart.png\/30px-Windowsstart.png","smallWidth":460,"smallHeight":460,"bigWidth":"30","bigHeight":"30","licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of a Windows icon.\n<\/p><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Public_domain\">Public Domain<\/a><br>\n<\/p><\/div>"} menu and select Power {"smallUrl":"https:\/\/www.wikihow.com\/images\/5\/5d\/Windowspower.png","bigUrl":"\/images\/thumb\/5\/5d\/Windowspower.png\/30px-Windowspower.png","smallWidth":460,"smallHeight":460,"bigWidth":"30","bigHeight":"30","licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of a Windows icon.\n<\/p><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Public_domain\">Public Domain<\/a><br>\n<\/p><\/div>"}. Hold ⇧ Shift as you click Restart. Navigate to Troubleshoot  Advanced Options and click Restart.  Press 4 or F4 at the menu to enter Safe Mode. If these steps don't work, see Activate Safe Mode in Windows 10. A list of scan options will appear. This starts the scan, which may take several hours to complete. Alternatively, you can select Quick Scan to do a short scan of the areas of your computer most likely to contain malware.
