I took a moment to look at Ace Utilities and I have to tell you straight.
You got took.
Everything they charge for and put in a pretty little package can be accomplished with a few well known, well established free tools. CCleaner ATF-Cleaner MRU-Blaster Defraggler
These 4 programs alone
will do more for you in the long run and are far far far more safe than some $30 dollar piece of Eye Candy Wrapper Ware.
Another $30 piece of garbage that is touted as "Recommended by Industry Experts"?
Who exactly are these experts, and what exactly are they experts of?
"I'm an expert in clicking on desktop icons that appear out of nowhere when I visit risqué
sites" WOO HOO.
Last Edit... The only other point I wanted to make was that you have to realize that almost all of these sites that advertise these kinds of tools are actually getting paid for their reviews. Not all, but the largest majority of the big commercial sites like Cnet do get paid for their recommendations. Again, maybe not all, but I bet it's a large majority.
