Why won't Bitdefender let me access my online account any longer?

Could you provide us with your bank name and its website so we can check if it’s being blocked on our end?

Additionally, If you believe that a website or file has been incorrectly blocked by Bitdefender, you can share the details with our malware researchers by filling out the form at the link provided below:

If the website or file is indeed incorrectly blocked, the detection will be removed within a maximum of 72 hours. However, if the detection still persists after 72 hours, please consider the website or file as malicious, as determined by our malware researchers, and the detection will remain.

Alternatively, for the time being, you can exclude your bank's website in your Bitdefender product by following the procedure outlined in the link below
