I actually saw the thing before Symantec had posted def's for its detection. And this scares the heck out of me.
The false impression of being safe and secure in Anti-Virus software was manifested last week. The fact that a bug could spread prior to def's being updated on a corporate network is a big bad wolf, huffing and puffing getting ready to blow the houses down.
I work in a straw house, I recommend you build brick houses.
