It looks like Google is going after malware writers that are manipulating Google Trends to get their pages to show up as top results in search queries. vnunet.com reports that the number of malicious Web pages showing up in queries of popular search terms on Google Trends has declined.
McAfee senior threat researcher Craig Schmugar says,
"It appears that Google may have squashed those attacks ... The pages that were coming up while searching Google seem to be purged from Google's index."
Google has confirmed that the offending pages have been removed.
