Gerardo, I have the same set up as you.
I was thinking the same as mczdsm: it is not that Updox caused the problem, just that it imported the fax that contained it. (You wouldn't say Gmail was the source of the problem if it came in an email attachment).
The urgent message for now, already transmitted to our staff, is NEVER click an attachment in Updox.
Just like you don't click it on an attachment in a suspicious email... but in Updox NEVER do it.
