Just pushed a change to fix the multiple new infections thing. It won't take effect until the affected user actually loads a page, so you may still see some around for users that haven't logged in or whatever.

I took the site down for a few minutes to take a backup of all of the hex data just in case something goes wrong with this code; if it does all hexes will be rolled back to then. But I'm confident it will be fine! :)

ALSO: Please note that HAs are cached for like five minutes or so, so your HA might look like it still has multiple infections but that doesn't mean it does.
