I would like to say that ever since I began using A1Click Ultra PC Cleaner, my PC has worked very well. A1Click does a great job in minimizing all that "stuff" that tends to accumulate on a PC. It's a great preventative maintenance program that you can set to run automatically that'll keep your machine running better and cleaner.
I purchased it for my daughter's PC as well. Whenever she comes to me complaining, "Dad something's wrong with my lap top..." The first thing I do is run A1 - and nearly everytime, her PC is full of crud that A1 sweeps out. (I don't have hers set to run on auto)
