Confirm it, Ransomware Shield adds the app to your Exceptions list itself and there's nothing else to do.Ĭontrolled Folders could be better, then, but it did its core job, keeping us safe from a threat that the antivirus engine missed. Controlled Folders simply blocks everything it doesn't recognize, and previously we've found some legitimate programs refused to run until we manually added them to an Exceptions list.Īvast's Ransomware Shield is smarter, more like a firewall when it detects an unauthorized access to a folder, it alerts you, but also asks if the process is legitimate. This time, Defender displayed an alert when our ransomware tried to access the folder, and it wasn't able to encrypt any documents. For more information, see Stay protected with Windows Security. It includes Microsoft Defender Antivirus, an antivirus tool that helps protect you against viruses, ransomware, and other malware. We turned Controlled Folders on, added our test folder to the list, and ran the ransomware simulator again. Windows Security, formerly known as Windows Defender Security Center, is an app built into Windows 10 or 11 that helps keep your PC more secure.
Fortunately, Defender has a second layer of protection in its Controlled Folders feature (Security Center > Virus & Threat Protection > Manage Ransomware Protection.) Turn this on and it automatically blocks unauthorized apps from accessing key document folders (Documents, Pictures, Videos, Music, more) and you can easily add more. Microsoft Defender Antivirus (formerly Windows Defender) is an antivirus software component of Microsoft Windows.It was first released as a downloadable free anti-spyware program for Windows XP and was shipped with Windows Vista and Windows 7.
