If you have purchased a new Avira product that replaces your existing Avira product and the runtime of the previous product is not yet finished, the remaining time does not expire.
When purchasing the new product, the remaining time of the previous product will be converted into monetary value of the new version. The end date of the new license is then extended by the term, which corresponds to the calculated amount.
A currently installed Internet Security still has a 3-month remaining time.
The license of the newly installed Prime version would end on 21.05.2018.
The 3-month remaining time of the Internet Security is converted into the monetary counterpart of the amount of the Prime version. This amount gives a term of 1 ½-month.
The 1 ½-month are automatically added to the final run time of the Prime version. This results in a new lead time of the Prime Version as of 08.07.2018.
