Another possibility is mwsock.dll is infected. See https://www.file.net/process/mswsock.dll.html

hi wayne,

replacing mwsock.dll didn't work and we finally got a chance to format the machine and upgrade to thunderbird 52.

but, thunderbird again started crashing and mswsock.dll is the only dll mentioned in the new crash report as well -> https://pastebin.com/8eaUgXnc

the new crash report also mentioned lightning, which we then removed but the crash continued.

any clue?
