this is the third time this morning that I've come across a Avast! URL:Mal warning just browsing the internet normally...
URL:mal means the website is on a block list, for whatever reason.....it does not have to be infected
there are several online tools that can be used for checking the URLs
and if you want a virus check, this is the guide to follow. http://forum.avast.com/index.php?topic=53253.0
