Certified versions can be updated using one of two methods:

  1. Via the mirror created by a certified version of the product.
  2. Using the drwzones.xml file that leads to certified zones.

Versioning and the originality of files is very important if a certified product is installed on an isolated computer. Updating a certified version via the mirror that was created by the actual (release) version of the anti-virus will change the checksums of the executable files and lead to the loss of Information Security System certification status. The drwzones.xml file, taken from the anti-virus that was installed from a certified distribution, will contain its own update zone. During the mirror creation process, it will be used to load database and component updates. Using a release drwzones.xml will lead to the loss of the certified status.
