I never faced a problem in uninstalling Kaspersky products ever till now but they have provided a removal tool specially for Kaspersky products.At times one may face problems in uninstalling the Antivirus,Internet Security or other products.Few members are facing problem in uninstalling the Chinese version as its blocking many programs and they cant understand the language whether to allow or block a particular software.
In this kind of scenario the best solution is to use the Kaspersky product removal tool,you can simply download the removal tool from the below link
http://support.kaspersky.com/downloads/utils/kavremover.exe
Just run the tool on the computer where a Kaspersky product is installed.It will detect the installed software,type in the verification code that it displays,incase you dont understand the displayed characters simply click the refresh button on the right hand side of the character screen to get new code and then click on remove.After restart your computer will be free of Kaspersky software`s traces including the registry items.
