How do I prevent Virus Blocker from scanning some websites?

To prevent Virus Blocker from scanning a website, add it to the list at Apps > Virus Blocker (or Virus Blocker Lite) > Pass Sites.  Sites added here will not be scanned for viruses.

Sometimes Virus Blocker's definitions will generate false positives. For example, we've had occasional reports that something in an Adobe update is caught as a virus. If you've verified that a site is a false positive, you can add it to this list and it will not be scanned.

You can also submit a particular URL to BitDefender for verification using this tool: https://www.bitdefender.com/business/submit/
