It adds another layer of defense by implementing Windows Defender Security Center in Windows 8.1 and beyond. Microsoft takes a different approach to protecting antimalware services.

Those vendors that have released patches include Malwarebytes, AVG and Kaspersky Lab. Not all impacted antivirus vendors have released patches for the Microsoft Application Verifier vulnerability. Check for the verification tool's patches The researchers injected arbitrary code and registered a malicious DLL for a process associated with a product.
