I have multiple email accounts within Thunderbird. On only one of them, whenever I open one of its boxes, like the Inbox, I get a warning from BitDefender: Suspicious web page detected. Online Threat Prevention. The webpage https://u8799275.ct.sendgrid.net/ has been detected as suspicious. Although the page is not blocked, it is not recommended to continue browsing this page. Accessed by: thunderbird.exe

This happens even though I deleted all the trash. Any idea why this keeps happening?

Ok, I clicked the link and got a 404 page not found error. SO I think we might have a bit defender problem.

Looking at https://sendgrid.com/ it looks like a marketing mail sending service, it also probably embeds web bugs in the email that allow tracking of the mail, fairly normal stuff. But bit defender might to set up to flag web bugs. I don't know as I do not use the software.
