Somehow, all desktop icons on my Dad's computer changed to Adobe and so when we try to open something, we get the message "Adobe does nto recognize this" (paraphrasing message). Ex. Mozilla Firefox still has the words Mozilla Firefox associated with it but it has the Adobe Icon and when you click on it we get the message.
Don't really care why this happened, except to prevent it in the future, but most importantly, - HOW DO WE CORRECT THIS?????
