Hi Markus,
I'm sorry you are having the issues with our website. We have been getting reports from users who use Bitdefender regarding the same issue. They seem to be the only one with this problem.
Upon the further investigation we found that BD does not play nice with WordPress websites, and in particular some Woo commerce components. We have contacted BD regarding this issue, but it is hard as, unlike many other companies, they do not seem to have a way to complain regarding false positives. If you Google "bitdefender worldpress problem" you will see lots of posts on the issue.
This is how to correct this problem:
