Unusual security patch from Apple

Updates, or security patches, have been key to family PC security for a long time, but not for Mac owners. Until now. This patch for Macs is worth getting, Apple fans - the company recommends it. "The update fixes a pair of flaws that could be used to create a virus that spreads through a Web link sent via e-mail messages," CNET reports, adding the view of a computer security company that the patch is "extremely critical" because of all the hacker instructions for exploiting the flaws that have appeared in online discussions.
