+    <h3>Anti-virus Scans</h3>
+    <p>
+        To provide a secure environment to all Dynamo Package users, we have introduced anti-virus scans for new packages.
+        When a user uploads a package, it will be scanned for viruses and will only be available publicly once it has been flagged as safe.
+        The scan will happen during the package upload process and will not add to the usual duration of 10-15 minutes for the new package to be available online.
+        If your package is flagged as infected, the Package Manager search window will display a notification stating that the uploaded package has
+        been found to be infected and won't be published online. To make the package publicly available, check the files included with the package
+        and upload a new version through the Package Manager.
