Norton 360 crashes Thunderbird's retrieval of Gmail messages

Your older posting on the same issue is here: Your version of Thunderbird is the last supported version for Windows and its a 32 bit install as well. Making things worse is Windows 7 has been unsupported for ages now, meaning being internet facing its extremely vulnerable. Malware will look for these unsupported installs and begin pounding them with issues, downloading certificates is one of those vulnerabilities. Are you using OAuth to validate? SA
