There is a single detection on the result, which is a false positive caused by a minor security engine’s heuristic analysis. It is very common for newly released or minor software to be misidentified as a threat.
Major antivirus vendors like Microsoft, Kaspersky, and Bitdefender have flagged this file as completely clean. This software is completely safe to use.

FAQ

When is Lunatic Mouse useful?

Lunatic Mouse is useful when you want to automate repetitive clicking or perform clicks automatically at regular intervals.

For example, you can use it to:

Repeatedly click the same button when testing software or web pages
Automate repetitive clicking tasks and reduce manual effort
Click a specific location at regular intervals
Perform a specified number of clicks and stop automatically
Assist with routine operations that involve multiple preset click positions

With customizable click intervals, click positions, and start/stop controls, Lunatic Mouse can be adapted to a wide range of tasks, from rapid repeated clicking to periodic automated clicking.

Auto‑clicking doesn’t work in some games. Why?

Some games include anti‑cheat systems that block automated input. These systems may prevent cursor movement or auto‑clicking by detecting it as unauthorized behavior.

Additionally, games that rely on DirectInput or RawInput may not accept simulated clicks or cursor movement, which can also prevent auto‑clicking from functioning.

I want to auto‑click at a specific position, but auto‑clicking doesn’t start after the cursor moves.

When using “Auto‑Click While Button Is Held”, and you specify a click position:

Pressing the assigned button instantly moves the cursor to the target position.
Auto‑clicking begins only if the window under the cursor at the moment you press the button matches the window located at the target click position.

If these two windows differ, the cursor will move, but auto‑clicking may not start.

Solution

After the cursor moves to the specified position:

Release the button once,
Then press it again to start auto‑clicking properly.
