I know most people here know better when it comes to opening emails, but this was in the news today...

From FOXnews:

LAS VEGAS — Yahoo Inc. (YHOO), the world's largest provider of e-mail services, said on Monday that a software virus aimed at Yahoo Mail users had infected "a very small fraction" of its base of more than 200 million accounts.

The e-mail virus, or worm, has been dubbed Yamanner and landed in Yahoo mailboxes bearing the headline "New Graphic Site."

Once opened, the message infects the computer and spreads to other users listed in Yahoo users' e-mail address books, security experts said.


The e-mail containing the virus need only be opened — in contrast to most worms that are hidden in attachments and require users to take an additional step — to release the virus, according to computer security site Symantec Corp. (SYMC).

The Sunnyvale, California-based company advised users to update virus and firewall software on their computers and to block any e-mail sent from the address "av3@yahoo.com."

"We have taken steps to resolve the issue and protect our users from further attacks of this worm," Yahoo spokeswoman Kelley Podboy said in a statement.



It says they "took care of it," but they also recommend upgrading mail software.
