URL:Mal infection detected

[macaddict]

over the last few days I have received 6 of these map infection notices several times.  I understand it is Malware that was trying evidently to connect to the site  http://fga5050.viewcontact.com/dc/...  And avast prevented it from doing so.  What I do not see is how to find that malware on my system.  Two days ago I ran a complete scan and removed all infected files found.  Most were windows files sent through email as spam or a file downloaded.  Only three were Mac related.  I moved everything to the chest.  Where do I go from here to find the offending file?  Do I need only to run a scan of home, a full scan or a custom scan of some sort?

It's the other way around, the site is infected, avast! Is blocking access to the infected files on the website.
