If you think the website/ file is incorrectly blocked by bitdefender you can share the same with malware researchers by filling up the forum in below stated link
https://www.bitdefender.com/consumer/support/answer/29358/
If website/ file is indeed incorrectly blocked, detection will be removed in maximum of 72 hours and if the detection still remains after 72 hours, consider the website/ file as malicious by malware researchers and the detection will stay.

Can you elaborate more on your issue.
For years, I would go to the CIBC sign-in page, my bank card number and password would appear. I would hit the sign-on button and then my accounts would appear. Now a small page appears requiring that I verify my identity. I hit a button and they send a one-time verification code. I've cleared my cache and cookies. Apparently, Bitdefender finds the CIBC sign-in page suspicious. It's a small inconvenience, but is there smthg I can do to Bitdefender to skip this step?
