'Here You Have' Virus Slams Major Firms Spam worm halts work at NASA, Comcast By Rob Quinn, Newser Staff Posted Sep 10, 2010 1:41 AM CDT 8 comments Comments Work slowed in offices around America as inboxes filled with massive amounts of spam. (Shutter Stock) (Newser) – An email spam virus swept through corporate America's inboxes yesterday, causing servers to be shut down at major operations including Comcast, AIG, Disney, and NASA. The virus spread through emails with the subject line "Here you have," which contained a link that downloads a virus that sends the same email to everybody in a user's address book. The Department of Homeland Security is investigating, reports ABC News. Security experts say anybody receiving the "here you have" email should delete it and contact their IT departments. They stress that people should never click links in emails from unknown people, or even in suspect emails from people they know. "The fact that it managed to spread widely through various multinational businesses doesn't say a lot for the security savvy of the workers," notes Neil Rubenking at PC World.
