MILLBURN, NJ - Businesses, schools and individuals are all warned against a virus spreading through people's contact lists via Google Docs. The seemingly legitimate invitation to view a document through Google Docs appears to come from an existing contact and then spreads as soon as the user clicks open.

The Atlantic notes that "Several IT experts are describing the attack as huge, startlingly fast-moving, and perplexing." 
The Millburn Board of Education sent out an email warning students and parents about a virus spreading through Google Docs and encourages users to delete the emails immediately. Surrounding towns and organizations are following suit, warning everyone in their contact lists against opening any Google Doc invitation. 

One line of defense is to adjust security settings on Google's security page. In the 'manage apps' menu, you can deny access to untrusted apps if that setting is not already engaged.
