Avast today updated its definitions and introduced a false positive that labeled legitimate, and non-malicious, sites as infected with the the HTMLcript-inf threat. This would cause pages not to load properly while Avast issued warnings. Some of the sites affected by this false positive include Wikipedia, Yahoo, PCWorld, and Youtube. https://blog.avast.com/2011/04/11/false-positive-issue-with-virus-defs-110411-1/
