Malware with fake or misleading anti-malware user interfaces (UIs) are detected. Processes running on a computer system are monitored and their window creation events are detected. The structures of the created windows are retrieved to detect presence of UI features that are commonly presented in known fake or misleading anti-malware UIs (“fakeAVUIs”). If a window includes a UI feature commonly presented in known fakeAVUIs, that window is determined suspicious and additional tests are applied to determine the validity of information in the window. If the information in the window is determined invalid, then the process that created the window is determined to be malware and a remediating action is applied to the process.
