Bd Antivirus 2015 Plus Uninstall

Hello.


I am using windows 7 home premium.


I uninstalled the BD in order to restore my system.I chose the option of future re-install.


When I try to re-install the BD, I keep getting a remark saying that a previous version is already installed.When I tried to uninstall the BD that is still on the control panel,it would not let me do it!


How do I solve the problem?


Thanks,


Arye
