This prntshot of that, http://prntscr.com/397z6w This is 2nd time it has been attacked like this, last month also my hosting provider told me that bulk emailing has been done from this domain and so . !! How to resolve this ?
Pretty sure spam =/= malware. Do you have webmaster tools linked to your site? Google is usually good at detecting malware like that. Try rebuilding your site from scratch, and rechecking it in WMT. If all else fails, change hosts.
