Hi trentsc,
When the site is as you state malcode free and an avast team member agrees that is the site’s status,
avast! is known to quickly react as with a next update even, so send your report with a reference to this thread.
We here are just volunteers with a bit of expertise and relevant knowledge,
doing this for the “good of our soul” and the avast! community. 
Hope your site will be unblocked soon,
best greetings,
polonus
