Sites blocked - MAL:Url

Following sites come up as blocked in avast!

australianfatshion.com
ginuary.com
nicholosophy.com
rynneviews.com
tasmemia.com

They were hosted on a different server until Thursday. I believe the old server (shared host) had exploited sites. The current server (dedi server) is clean. Sites also check as clean.

Two other sites hosted on this server are:

definatalie.com
fancyladyindustries.com - already being discussed at http://forum.avast.com/index.php?topic=129705.0

Both sites appear in CLEAN MX but I can’t see any exploits in the sites themselves.

All sites are running Wordpress 3.5.2.
