This incident has been resolved. Google's review of our infrastructure was successful and they no longer report banners or unsafe downloads for our domain. We will keep certain attachments blocked on inbound email (replies to conversations by email or email forwarded to us) for the time being, until we investigate changes to our anti-virus scanning for inbound email

Monitoring
We are continuing to monitor this situation for resolution; at this time we are awaiting review from Google to remove the banner from emails sent via Intercom. In parallel, we also continue to work on multiple engineering tracks to resolve this issue and minimise the chance of reoccurrence. At this time we have no ETA on the completion of the Google review, but will update this incident on any status changes.
