Earlier today TBird 38.3 just stopped working, stuck when a new email notification popped up. Tried EVERYTHING that I could find in regards to the general problem to no avail - started with "-safe-mode" - disabled new email notification - disabled anti-virus (Avast) - disabled add-ons (using Lighting calendar, the buildin one) - rolled back to 38.2 - installed 40.b2 as I had installed (but not rebooted yet) Windows updates (running Windows 8.1/64, 8GB RAM), did a system restore to before the updates and then through the above list again

It might get as far as receiving new email, but usually in 60 secs max, it will just lock up. Task manager shows a constant 25-26% CPU usage and a somewhat fluctuating memory usage between 240 and 280MB

There are 3 GMail IMAP accounts, 1 GMail POP account and my own, local IMAP account.

All was working perfectly until earlier today... :-(

See the notes on avast here https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues#AVAST


I think that might be a good place to start.

As I mentioned, I disabled Avast, didn't make a darn difference...

And just FYI, Seamonkey 2.38 after importing from TBird 38.3 is working fine, another reason why this is NOT an AV related problem....
