I am trying to install Bitdefender Total security on Pc window. everything works until it requires to uninstall current security apps which was Kasperski. when click on "uninstall" I get a message stating "this action is only valid for products that are currently installed". I have used both window and Kavremover tool to uninstall Kasperski but still it does not work. Would you please help? It appears I don't have any old kasperski on my system but, still bitdefender installation fails. Thank you!
