SO I tried a few apps - pocket informant, worldmate and viigo that I tried and deleted. There are now icons with a green arrow in my downlaods folder and the software is labled Pocket Informant (Archived), etc.
I can see no controls to delete these archives from my system.
Thanks for the info Midnightdraven. Tried various solutions from various sites without success. Finally a simple solution that actually worked. Much appreciated! jimm367, accept "Reboot Now" after delete is complete and you should have no problems.
