'Who's there?' See what's persistently installed on your Mac.

Malware installs itself persistently, to ensure it is automatically executed each time a computer is restarted. KnockKnock uncovers persistently installed software in order to generically reveal such malware.

To use KnockKnock, first download the zip archive containing the application. Depending on your browser, you may need to manually unzip the application by double-clicking on the zipped archive.

To run the application and begin a scan, simply double-clickKnockKnock.app.

Press the 'Start Scan' button to instruct KnockKnock to scan known locations where persistent software or malware may be installed. By design, KnockKnock simply lists persistently installed software. Although by default signed-Apple binaries are filtered out, legitimate 3rd-party software will likely be displayed.

The left-handle table contains the categories of persistent software that KnockKnock scans. Each row contains the name and brief description of the category, and the number of detected items. Clicking on any of the categories will display the items for that category in the right-hand items' table.
