When downloading messages if there is a trojan in an email Bitdefender quarantines my entire inbox and subsequent emails in the same download have no inbox to write to so give an error. There is a work around but it is a pain. I have to do the following. 1 Log in to webmail 2 Delete suspect emails manually 3 Delete the popstate.dat file 4 Rerun the download. This is a pain and I run the risk of losing older emails. I have switched off antispam in Bitdefender to no avail. Running 64 bit Windows 11 with the latest versions of Thunderbird and Bitdefender. Hope someone can help.
