Internet security (AIS) has different avast versions 7.x, 8.0 and 9.0 (a.k.a avast Internet Security 2014), so the information being asked for relates to the version number AIS, 8 or 9.
The reason this is important, is if it was the older version 8.0, then it may not have been compatible with windows 8.1 and may have been removed.
