Network Shield still blocked website after it was fixed

Hello everyone,
Few months ago our site (udomfurniture.co.th) was infected with some malware (our users told us and they use avast! as their av, that our site was blocked) so we decided to created our whole site from scratch and use avast! to scan all local sources file. Avast! report that “NO THREAT FOUND” so we uploaded our new files hope that our site can be access again but avast! still blocked the site indicating that it’s URL:MAL infection.
Using sucuri sitecheck: http://sitecheck.sucuri.net/results/udomfurniture.co.th , Verified Clean

what step should I do next?

Thank you for every supports and comments
