Please note that it is unnecessary to uninstall the trial version when subscribing to a registered version of F-PROT Antivirus as these programs are exactly the same package.

To subscribe from the trial version to the registered version, please do the following:

1. Buy a subscription within the program or buy directly from our website at https://secure.f-prot.com/cgi-bin/buy. The subscription is valid for 12 months which is the typical subscription period online.
2. You will receive a customer number from our sales department after you successfully buy a subscription. Use your customer number to login to the Customer Zone. In the Customer Zone, view your Subscription Key and enter the key in the program to be able to download and install updates. For further information, see How to obtain your new Subscription Key and enter it into the program..
