After an iAVI update has been done, is there a way to undo it, i.e. to roll back to a previous iAVI version?
The original file is normally backed up in /opt/avg/av/update folder. There should be something like this #/#opt#avg#avl#var#data#incavi.avm. You can rename it to /opt/avg/av/var/data/incavi.avm. Otherwise there is no comfortable way to do it. Please note, if you overwrite the file the next update will download full version of the file. In case of iAVI it could be ~60MB.
