YahooMessenger.exe has more than 15 characters in it so AP exclussion will not work till you have HF "HF613356" as per KB#: KB7020. Did you try adding with Wildcard exclussions like Yahoo*.exe or YahooMess*.exe etc.
Thank you for your attention
but, unfortunatelt, it does not work correct. after I add yahoo*.exe and yahoo*.* I see my problem again and lasy message:
