Agreed that avast is on the short end of covered programs but then again avast mission is not to catalog and notify every possible iteration of possible software programs one can run on their systems. Actually, as there have been issues with Secunia in the past I have found this program works well as it is self-contained and does not require installation to do its thing: https://patchmypc.net
Like Secunia it will auto-update and install the latest known secure versions of programs.
