While we haven’t seen attacks in-the-wild actively targeting Windows Defender Antivirus, we take these reports seriously. Security researchers both inside and outside of Microsoft have previously identified ways that an attacker can take advantage of vulnerabilities in Windows Defender Antivirus’s content parsers that could enable arbitrary code execution. In order to inspect the whole system for malicious content and artifacts, it runs with high privileges. Why sandbox? Why now?įrom the beginning, we designed and built Windows Defender Antivirus to be resistant to attacks. We encourage researchers and partners to try and examine this feature and give us feedback, so we can fine-tune performance, functionality, and security before we make it broadly available. It is available to Windows Insiders today. While it was a tall order, we knew it was the right investment and the next step in our innovation journey. More importantly, we had to identify high-risk areas and make sure that sandboxing did not adversely affect the level of security we have been providing. It was a complex undertaking: we had to carefully study the implications of such an enhancement on performance and functionality. Putting Windows Defender Antivirus in a restrictive process execution environment is a direct result of feedback that we received from the security industry and the research community.
With this new development, Windows Defender Antivirus becomes the first complete antivirus solution to have this capability and continues to lead the industry in raising the bar for security. Windows Defender Antivirus has hit a new milestone: the built-in antivirus capabilities on Windows can now run within a sandbox.
