Chrissie,
Keep away from it.
It is one of those programs that find faults by the barrow load using it's free scanner then you pay through the nose (or credit card) to get it fixed.
If you computer is running good enough for you then just carry on as normal. If it starts slowing down or showing signs of wear then post the symptoms on here with as much info as you can and youu will get clear advice about sorting your problems using FREE software.

Chrissie,
Just read your other post and see why you were asking about this program.
Must go out now but will be back later and will reply in the other thread.
