You can often see some autoclickers with malware for download, so my way to avoid this was to create my own.
I created it for personal use, so expect some flaws in the program. I used windows forms interface, that means I used C# as the programming language, basically.
I don't know if I am going to update it, since it's for personal use, and I really don't need anything more, but I can think about maybe changing the activate button or the pressed button, since doing it isn't any trouble.
Anyway, feel free to download, modify, upload a new version...
