Hello - if the constant guard executable can't be found, the link between the icon and the executable is broken. The best solution is to remove the application and reinstall so the link can be recreated. To do this, just go to your add/remove or programs/features control panel, remove the application, and when prompted, "SAVE" the secure programs file. Reinstall the application from www.comcast.net/security and that should resolve the issue.
The broken link has absoutely nothing to do with the application, but something in your startup sequence - perhaps a browser change, broke the link to the executable (.exe) file, which is the actual connection from the icon to the startup file.
