Dear AVG,
I have just purchased through Pay Pal an AVG Internet Security 2015 for the amount of Euro 43.99.  The AVG Order Reference No. is 37-5472877 and the Invoice No. is 2902201491.  The invoice date is  18 June 2015.  I have a problem to install the software and I have not received yet an email with the licence key.
Thank you in advance for your interest.
Regards,
Eugenio Cutajar

  1. Your computer will be restarted automatically. After the restart, AVG Remover will finish the uninstallation.
    NOTE: Once the AVG Remover Tool has done with its process. Please go to the drive where you installed this tool and look for a folder named as "AVG Remover" and I request you to delete it manually.
    4) Second step is to use AVG BFE Fix tool. To download AVG BFE Fix Tool please click on the following link: http://download.avg.com/filedir/util/AVG_BFEfix.exe .
