I cannot activate Bitdefender..

I currently have Malware anti virus. Do I have to cancel that in order to activate bitdefender?

Are you talking about Malwarebytes?

In order to install Bitdefender, you will need to uninstall any other antimalware product you are using, as having multiple antimalware programs can affect your system's performance.

If you still want to continue using both, you will first need to install Bitdefender and then install the other antimalware product. Make sure to add exclusions for both antimalware programs in each other's exclusion list to prevent any conflicts.
