Hey all, I checked our SmarterTools email server running the latest SmarterMail build (what most refer to as 17) and I can see we have viruses listed in our quarantine tab. If you're using a browser like Chrome can you open up the developer tools inspector (F12, or Ctrl+Shirt+I), refresh the browser, and see if there are any errors reported in the console or network tabs.
If everything looks fine I'd suggest opening up a support so we can troubleshoot the issue further. Thanks.
