    I apologize if any of this is already known or not applicable
    to this list, but i found something that disturbs me today
    about grokster.
    
    While going thru my registry today, i noticed the reg entry:
      SOFTWARE\Microsoft\windows\currentversion\run
      "dlder"="C:\winnt\explorer\explorer.exe"
    
    C:\winnt\explorer\ turned out to be a hidden folder, with one
    file "explorer.exe" (31Kb).  So i deleted the entry in the
    registry, PGP-Wiped the directory and EXE file, and rebooted.
    
    Upon rebooting, i noticed a "dlder.exe" hidden executable
    in my C:\winnt\ folder (i dont know if it was there before,
    but i think it was, i just didnt notice it).  
    
    After opening up explorer.exe and dlder.exe in an editor
    that displayed them as Hex, i noticed "clicktilluwin",
    which is a (supposedly) optional add-on piece of software
    that comes with Grokster.  I had installed grokster last
    month and used it once, disliked it, then uninstalled it.
    
    So it worries me that this "click till u win" thing that i
    told grokster *not* to install, is still hanging around.
    
    Then i called a friend of mine, who verified that he had
    the same reg key and hidden folder/files.  he deleted the
    affected registry keys and bogus "explorer.exe" and "dlder.exe"
    files and rebooted.  Then, he did a fresh install of Grokster,
    specifically telling it *not* to install "clicktilluwin",
    then rebooted, and there the registry keys and hidden files
    appeared again -- seems that "click till u win" is installed
    no matter what you tell grokster.
    
    I have no clue what these two binaries are doing to my
    system, and it worries me that they might be keyloggers
    (or something malicious).  I attached an email my friend
    sent to me after he did some research into Grokster, and
    now i am even more nervous.  It seems that the information
    he found about the company is completely bogus....
    (Please see attached email)
    
    For more information and copies of the two binaries
    that i found on my system, please go to:
