    "higly recommended"

    September 10, 2011  |   By sillyhermitcrab


    very easy to use,very easy to understand whats going on


    some stuff still seems scattered a bit though it is all organized.nothing major


    as an IT for hire,i download 4 programs on to each and every computer i repair-AVG free,Malwarebytes,CCleaner,and Defraggler.i inform all my clients that these 4 programs are what i use to maintain my machines and they do their job very well,especially for being free.i do recommend purchasing when you can or donating to Piriform.Piriform rocks.
