I have a programe (utility) name deep freeze, running on my system.
By some of my mistake, resulting the disappearance of icon in Tray area.
Without the icon I can not disable it. (Ctrl+Alt+Shift+F6 also not working)

I have terminated it from task manager but still no use.
Not visible in add/Remove program, or in start Menu.

Whenever I go for new installtion, it is prompting to disable it first, as
the program is running in the back ground.

Can you guide me how to disable it so I can uninstall/install it.

Many Thanks..
