Hello Fire! Firstly, I would like to thank you for writing up an appropriate comment regarding the support estimate for the 2014 version of Avast! prior to installing Avast! 2015.
As DavidR mentioned I agree with his comment! It hard to know it's estimate date on support. Best way for getting better protected is by installing the latest and most up-to-date avast! antivirus program. It offers better and greater protection, more new features, better streaming updates, and the list goes on and on... 2015 version got recently released.
