Thunderbird extensions can also be the cause, especially if you're using anything add-ons that manage your spam or junk emails. Because there are so many security suites, check your settings or options and see if there are any email settings that hijack Thunderbird. This is more likely if you're using an entire security suite that comes with antivirus, firewall, and email protection. Your security software is creating the folder. Any email you flag as spam will go into your Junk folder because you already received the email and that's the folder Thunderbird uses. That folder will be created if it does not exist. In other words, any spam received and considered spam from the server end will be placed in the folder that is expected. Most email servers will mirror whatever folders expected in Thunderbird.
