    If You can't clean Your pc manually, then don't use any cleaners at all. Can do more harm than good.

    I've Monkeyed around "On & Off", with this App for the Last Week.
    MY concern is an Internet Users Privacy. A lot of Guys shrug their Shoulders
    & give it the Big "I couldn't give a Toss".... Well,,, OK then..!!
    The Techy's will know what I'm saying, but Anyone who is reading this &
    Isn't fully conversant, will be lost.... BUT, It'll come.. Eventually.

    Index.dat .... Is what I'm talking About..!!

    Dependant On your System, But mainly the Browser you are Using.
    Index.dat files are Generated Every time you Surf. Some even as you Boot.
    They track Everywhere you go on the Web, & some of these Index files
    are stashed away in Super Hidden Folders on your System.
    You can delete them, IF you know where they are lol.. But in the Main you will need an App to get them off your System. MalwareBytes has "or did have"
    (File Assassin) as an Extra at one time. That will delete them.
    So...!! That's a very basic rundown..

    There ARE some Fancy App's which will Display ALL the Index.dat files...
    - Index.dat Suite (being one of them). But I'm here to help the Unknowledgable
    & Review CCleaner.
    (As a Test).. If you config CCleaner to JUST clear your Browser Under The Windows tab, & then uncheck everything else as well as everything under the Application tab. You will note that (dependent on your browser) Index.dat files is listed in the options.... 1) Run Analyze..... 2) Run Cleaner.

    If you do a search of your system now. You will see all the Index.dat files
    are still there..?? .. BUT .. They've all been Wiped Clean ... ~_^

    You cannot stop Index.dat files from being generated. Not even thru the
    Registry. You cannot CACLS or XCACLS them to be Unwritable. So if you're
    Freaky about Privacy, Get Downloading this App & Wipe 'em... lol

    There's a lot of Controversy about IF CCleaner "does or Doesn't" wipe the
    content, So here's a link & see what you think..??
    I read the content of my Index.dat files "Before & After" Running CCleaner.
    Contained Data "Before"... No Data "After"... (& the File size changed).

    Don't rely on what is said at, or My test...
    Do your own Tests..... Get some Privacy, & Keep Safe.

    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

  2. Aug 16, 2010 - 5:06 PM

    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?
