First, I've already opened a support case but I don't understand everything. As English is not my mother tongue, it's a little bit difficult for me to deal with such complicated licensing issues.
At the beggining of April, I downloaded a trial version of F-Secure AntiVirus from F-Secure website.
I decided to remove this product from my computer after only 1 day of use. I have understood that the trial version can only be used 1 time on a computer and won't work again after an uninstallation.
Then I came across a full F-Secure Internet Security licence from Ebay, for only 10 Euros. I have received the "Service Key" which is good.
When I tried to install F-Secure Internet Security, my key was recognized and I was able to install the product, with a 1 year validity. However, my TRIAL license was still listed in the product, and its expiry date was moving forward with each day (for example, 05/16 then a day after, 05/17...).
So I tried to uninstall and reinstall the product again to get rid of this trial key, but the more I install the product (on the same machine), the more "Trial License Key" were added to my product GUI. The valid 1 year key was still listed at the bottom of the list, but everytime I try to enter it into the "Activation wizard', it tells me that my key is valid but when I click on "Install", it tells me : "The trial license key was already used on this system" so I cannot get my key working.
Furthermore, I noticied that each time the "Device ID" for my account was different with each reinstallation on the same machine.
I've already opened a support ticket, tried Uninstall with UninstallationTool, tried the different Installers, without success.
I ended up buying an official license from the F-Secure WebStore and my new key is now working perfectly. But I still have my old key inused. Can you help me to recover the 1 year period on my old key, merge it with the new key or add it to the end of my other 1 year subscription ?
