This is a great program! I have used it off and on for years and I love it! It keeps my computer clean and reduces the amount of space that is used when a person surfs as much as I do.
After months and months, I finally set it up to automatically clean my system every day. Right now I am running it on a Samsung ATIV Smart Tablet with 4 GB of ram. I notice that it significantly slows down the other processes if I am doing something else.
Not a problem other than I forget that it is running in the background and when everything sort of chugs along at a slow pace, I realize why.
This is a product I would recommend for anyone to download and use!
