Lenovo Soundmax HD mute button issue

The system freezes, computer locks up if you try to either push the mute button on the keyboard or click on the mute box in the on screen soundmax volume control found in the tray. I’d like to keep Comodo but I will have to uninstall if I can’t resolve this issue. Please help. BTW, there have been 12,000 views of this issue on the other thread so I am not alone.
