Free early build 0.1

Find out what is really running on your computer.

Some software can watch your screen. Some lets a stranger take the mouse. Some of it is AI, working away without being asked. The scan reads what is on this machine and writes you a report where every line is a plain sentence.

Download the free scan (15 KB)

Windows 10 or 11. Nothing is installed. No account, no email address.

Three steps

Takes about a minute, and most of that is Windows asking whether you meant to do this.

  1. Unzip the file you downloaded

    Right-click it, choose Extract All, then Extract. You get a folder with three files in it.

  2. Double-click Run the scan.cmd

    A black window opens and counts through what it is checking. Leave it alone for a few seconds.

  3. Read your report

    It opens by itself in your web browser when the scan finishes, and a copy is saved to your Desktop so you can look at it again or send it to someone who can help.

Windows will warn you, and it is right to. You will see a box saying the publisher could not be verified. That box appears for anything downloaded from the internet that has not been signed with a certificate, and we have not bought one yet. Click More info, then Run anyway. If that sentence makes you uneasy, good instinct: open ImposterShield-Scan.ps1 in Notepad first and read it. It is plain text and it is meant to be read.

What it looks for

Four questions, asked of every program running, every background service, everything set to start with Windows, and everything holding open a network connection.

Can someone else control this computer?Remote-control software like AnyDesk, TeamViewer or RustDesk. This is the one that matters most. The support-desk phone scam works by talking someone into installing exactly this, then watching them sign into their bank.

Is something recording what you do?Keystroke loggers, screen recorders, activity monitors, and Windows Recall quietly saving pictures of your screen.

What AI is on here?AI assistants, AI models running locally, image generators, and agents built to act on their own. Most of it is harmless and you probably installed it. You should still know it is there and what it can reach.

Is anything acting by itself?Software that drives your browser, replays clicks and keystrokes, or launches from a folder anyone can write to every time Windows starts.

Nothing leaves your computer

Not a promise about how we handle your data. There is no data to handle.

What it cannot do

This is an early build and we would rather you heard the limits from us.

It will sometimes be wrong. Finding TeamViewer on your machine does not mean you have been scammed; plenty of people install it on purpose. That is why every result says where we found it and what it means, instead of just flashing a warning at you. If something in your report is wrong, tell us and we will fix the scan.

Something wrong?

Write to hello@impostershield.com with what the report said and whether you agreed with it. A report that got something wrong is genuinely the most useful thing you can send us.
