I recently updated to v 4.5 home edition. Subsequently, performance of Mozilla Thunderbird v 0.8 email has seriously degraded, such that previous sub-second response times are now consistently 4 to 6 seconds.
I have perused the Avast help and cannot determine how to resolve this. For example, a start menu selection for the Avast email protection configuration was specified, yet I do not have this selection. Also, I am unable to find anything in the settings options that allow me to turn off the email "protection".
At this point, I would like to retain the upgrade, but turn off the email protection, such that my response time returns to normal. Is there a way to do this? Or, do I simply need to back out the upgrade?
