Keyboard and/or mousehook could not be activated Topic is solved

[Sebastian42]

This question was also asked by someone else two years ago and got no answers. Suddenly Autohotkeys stopped working. I found that autohotkey.exe was missing. I re-installed the program, but that did not fix it. After searching Google I found a reference to mousehook.dll probably being malware. I did find it in \windows\system32\ and it was dated 2007. I deleted it, but reboot still triggers the warning "Keyboard and/or mousehook could not be activated" and Autohotkey still does not work any longer.
