My experience is that when an application is deleted from your system the icon in LnS changes from the application, or in some cases the generic, icon changes to a question mark. I have just changed from Avast 4 to Avast 5 and the update application has a question mark in LnS. See pic. Not a problem but I am just wonder why, and can it be changed? Or maybe I should ask this question in the Avast forum?
