No, I do not know anything about the program but I think I heard the program or seen it listed on a log. I dont think you need that program but it is your call.
PP and I have already mentioned decent alternatives, more will be on the sticky.

I have yet to see a single program that does everything (clean, repair and improve overall system performance) without coming short or even not too good in certain areas!

From most people's HJT logs, I noticed one thing, they have not done regular, adeguate maintenance on their system and waited till sh*t hit the fan and did wayyyyy too much (and possibly did them wrong too) which in return bulloxed things up instead of doing good.

Bottomline, doing the related maintenance periodically and in a correct way is just as important as doing the required maintenance itself.

Please wait for my sticky for further info. It, hopefully will be ready over the weekend (work has been murder lately).
