    How to Uninstall Kaspersky Antivirus 2011 silently

    I am using Windows 7 operating system on my computer and have also installed Kaspersky antivirus 2011 on my pc from quite some time. Now I am looking to uninstall this antivirus from my pc silently. I have already tried to remove this product with uninsallation string along with different commands like /qb! /norestart but it keeps asking to stop Kaspersky application. After I exit from the application the command works normally. The Kaspersky service also cannot be stopped, is there any solution for this issue? Thanks

    Some errors might occur when deleting Kaspersky Lab products via Start > Control Panel > Add\Remove Programs (Add/Remove Programs). As a result the application may not uninstall correctly or remnants of the application may remain in the system. In order to fully remove the installed Kaspersky Lab product, use the kavremover utility. You can easily download the utility from this link here - http://support.kaspersky.com/common/...el=1464#block1

    There is a client/server application on which I was working that removes the supported Antiviruses from client machine. For that I used to send commands like "MsiExec.exe /X{66F1F013-008F-4875-B283-5A814B820347} /qb! /norestart" to client and it will immediately remove the detected AVs from the client machine. You can try to use the same command to remove the Kaspersky Antivirus 2011 and it will ask you to stop Kaspersky application running in the tray as well.

    Search in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for Kaspersky

    The product KAV2011 was listened under "DisplayName" and then copy the value from "UninstallString" into a batch file like:

    MsiExec.exe /X{2944038F-8B5B-4861-9C26-8267254A339C} /QN

    Then deploy this batch to this clients.
