Rapport is compatible with each of these products on its own.
However, Rapport is not compatible with the combination of Zone Alarm and Avast installed on a single PC.
We have contacted the relevant vendors (Avast & Zone Alarm) and they do not approve the combination of these 2 programs on one system, and so we are not able to have them comply with our compatibility requirements.
Therefore, we recommend using only one of these products in combination with Rapport.
