4.0.437 causes triplication of messages in Thunderbird inbox

Our users are reporting that upon updating to NOD32 build 4.0.437, that all new messages that they open in their Thunderbird inboxes become triplicated. I have been able to reproduce this problem on all of my workstations. The issue cannot be reproduced on 4.0.424 builds. If we disable Thunderbird integration in NOD32, the problem stops, but this is not a solution that I want to push out by policy.

I suspect that the mail corruption bug fix Thunderbird that is included in the 437 build is having unforeseen side-effects. Is anyone else seeing this problem? Is there a fix in the works?

 

This has already been discussed here so we'll keep further discussion in that thread.
