I'm seeing a warning about bitdefender.site in my browser. Is this a problem?

The warning you're seeing could be a false positive, especially if you're using Bitdefender software. However, it's still important to investigate. Check if the warning is from a reputable security tool. If you're unsure, temporarily disable your browser's security extensions and try accessing bitdefender.site again. If the warning persists, it might indicate a potential security issue, and you should consult with a cybersecurity expert.
