What it will look at

• Every mods folderEvery jar in the folder the game is using is compared with the published version of the mod it claims to be. Other launchers and instances too, plus x-ray packs and cheat versions.
• Run history and downloadsPrograms Windows remembers being started, the browser's downloaded jars and programs, cheat sites in the history and DNS cache, and what starts with Windows.
• Cheat clientsKnown cheat client files anywhere in the user's folders, checked by what is inside them. Also their config folders, and whether one looks like it is running.
• Service memoryCheat-related strings in the memory of Windows diagnostic services, which remember what ran recently.
• Accounts and altsMinecraft accounts found in launchers and in game logs, with the main account marked.
• Mouse softwareMacros and profiles in Logitech, Razer and other mouse software, with when they were last changed.

• PowerShell historyCommands in the PowerShell history that delete files or clear system records.
• USB and other drivesThe programs, jars and archives on USB sticks and other drives that are plugged in, checked by what is inside them. Also USB devices plugged in recently and files opened recently.
• VM and sandboxSigns that the scanner is running inside a virtual machine or sandbox instead of the real PC.

It does not record keystrokes. The only picture it takes is of the Minecraft window, never the rest of your screen. The full list of what is stored, and who can see it, is on the privacy page.
