avast webshield is blocking my business website

Avast Webshield is blocking my business website showing URL http://www.m-media.com/|>{gzip} Severity High Status Threat:JS:Blacole-DT[Expl] Action Blocked

I have scanned it with Google Webmaster Tools, http://sitecheck.sucuri.net/results/m-media.com and http://safeweb.norton.com/report/show?url=www.m-media.com

They all say the site is fine. So what do I need to do to get Avast Webshield to stop blocking my site? Is there a specific file I can edit or delete? Or would you all agree that Google, Norton, and Sucuri are right and unblock it?

Thank you!

This may be a false positive.
