DimScreen.exe False Positive

[TheBlueRaja]

Hi,

I use a program called DimScreen which dims the monitor screen for you should you wish, it can be found here:-

Its a program i run at start-up.

Malwarebytes has just informed me automatically, perhaps due to a background scan, that the program is a malicious process and identifies it as Trojan.Autoit although i've been using this for a week or so now.

Is this a false positive?
