I don't know fella's - I downloaded Auslogics Defrag free without a hitch today. It all installed perfectly with no yelp from Avast.
Its one of those computer hiccups we all get. I am sorry to trouble you, but yesterday Avast blocked it and today Avast liked it. Well, you can'y win 'em all can you ?
All I can do is thank you for responding and leave with - Zip-a-dee-doo-dah, zip-a-dee-ay
My, oh, my, what a wonderful day.
