Cybercriminals are circulating a new piece of fake security software that spoofs a Microsoft security tool. It’s called the “MS Removal Tool.” If you see a pop-up ad or an email for the “MS Removal Tool,” ignore it.
If you already have this malware on your computer, you might not be able to access Internet Explorer or any other programs.
You will have to boot your computer into Safe Mode. For detailed step-by-step instructions use another computer or smartphone to read Microsoft Support: How to remove the MS Removal Tool from your computer.
If you can access Internet Explorer or another web browser, use the Microsoft Safety Scanner to scan your computer and remove the MS Removal Tool.
