US Patent 11687649 Securely and efficiently providing user notifications about security actions

A security agent executing in kernel mode may receive a request from the anti-malware component executing with low privileges in user mode, and, in response, the security agent may perform a security action with respect to a malicious file detected on the computing device. The security agent may then assist the anti-malware component in providing a user notification about the security action by obtaining, on behalf of the anti-malware component, a user token associated with the user session in which the malicious file was detected. The anti-malware component can use the obtained user token to request a pointer to a Component Object Model (COM) interface for outputting the notification in context of the appropriate user session, which allows for securely and efficiently providing the user notification.
