Kaspersky Blacklist patch prevents clldr.dll detection from future scans. Unlike other versions this is not executable. This iz .dll file so you need just copy/paste.
WHAT DOES THIS DO?
+ Enables you to use Keys that have been blacklisted

HOW?
+ Without getting too technical, clldr.dll removes the KEY verification process.

HOW TO USE?
+ This assumes you have Kaspersky installed (if not.. download below, install, and proceed)
+ Click Settings
+ Uncheck Enable Protection
+ Click Options
+ Uncheck Enable Self Defense
+ Press Apply
+ Close Kaspersky
+ Completely Exit Kaspersky (Right click icon and select Exit)
+ Go to Kasperskys installation directory
(i.e. C:\Program Files (x86)\Kaspersky Lab\Kaspersky Internet Security 2010)
+ Rename clldr.dll to clldr.dll.bak
+ Copy & Paste Provided clldr.dll into the Installation Directory
+ Complete
+ Now you can use any Keys Smile

Supported windows version
+ Stable with XP and Seven,Vista.
+ I, personally, tested on XP Pro SP3 (x86) and Windows 7 Enterprise with no problems at all
