I’ve been curious about a way to remove [Possible Spam] from e-mail subject headers as well. I’ve been using the free Avast for awhile now (up to current version) and my e-mail client is Thunderbird. It’s not that big a deal, and the only time it’s an issue is due to me forgetting to delete that part of the subject line when replying to an e-mail, but if I could just discontinue that particular option, it would save a little embarrassment every now and then. :slight_smile:
