Bit Defender Security

Chumvi

I have bought Bitdefender today and I have not yet managed to install it because I get an error just after the BitDefender security step.

I receive a message saying that I have another security installed but I can´t discover this 'another security".

Is it possible to skip this step? Is there another solution for me? How can I get help from BitDefender ?

I am almost giving up the BitDefender antivirus...

Thanks in advance
