When I review stuff for The Porn Dude, I often find that I go over a number of things that I have never seen before. This is both a blessing and a curse, because while I might not have had previous experience with the product, it also means I don't have any preconceived notions or bias. When it comes to CCleaner however, I'm very much an impartial reviewer.
I've used this product for a number of years, because to honest, it's so damn good at what it does. The basic premise is this: you download the program, install it and run it to clean up a lot of your PC. It does multiple things including deleting browser caches, redundant registry information, nasty programs you don't want and even allows you to select what starts when your PC boots.
Put simply, it's a lifesaver for anyone with a PC that's more than a few months old and could do with a bit of tweaking. CCleaner has more than 1 billion downloads in its history and to be honest, this thing is the best damn product in its category. No questions asked. In fact, the only way CCleaner could be improved is if it sucked your dick while doing everything else.
