    This software is garbage stay clear away from It unless you want your PC to be completely destroyed. There are much better programs out there then this crap are far better to use and no its not Norton.

    What happened to 'Slim' builds? Now just main larger install or similar size portable. I'm still using 5.11.5408 Slim build(the last slim build). I may have to find something else.

    I stand correcfed. It IS cleaning the Flash cookies -- it's leaving a "settings" file, which also carries an ".SOL" extension, which I thought was a cookie

    How about adding an option to remove FLASH COOKIES?

    I haven't used this product in a while and when my PC gets full, I'll use it to clean clean it out.

    CCleaner doesn't install but Yahoo! toolbar. It's recommended that you should install the Slim version.

    Not only that, but it tries to install on your computer! :-O

    I hear you! I had to reinstall my OS because I used the registry cleaner! With such small files being installed into the registry, just leave it alone. There is NO WAY that any registry cleaner could possibly know all of the file names that program writers make up and install. BAD IDEA!

    Everyone here seems to have lots of love for this program, but today it killed my wife's laptops registry. I think it would of great help if the registry list of "problems" had a collumn with the origin of the file, so you can see if it is a valid entry, or something that really should be deleted. because lets face it, does anyone really know exactly what every dll file does- by name?
    How do we make an informed choice on which to delete or not delete?
