AVG migrates my mozilla thunderbird from version 60.5.3 to 78.4.3 and I do not know how to avoid that. Version 60.5.3 is not compatible to 78.4.3 and I would have to start my thunderbird from new and would loose all my data (adresses, emails etc.). So I install version 60.5.3 from my downloads and all works fine again till AVG does it again. So either how can I tell AVG to leave my thunderbird in peace or how kann I migrate my data from 60.5.3 to 78.4.3 wich would of course be the better solution.
