I had an email from Orkut this evening telling me I had a new scrapbook entry. I don't really use Orkut, but I signed up a while back, and friended a bunch of people I know. The scrapbook entry was a bit cryptic:
2008 vem ai... que ele comece mto bem para vc
I still don't know exactly what it means, I'm assuming it's Portuguese. Babelfish wasn't any help. I won't mention who I got it from, but I will admit that if you are friended by me on Orkut, I probably gave you a copy too. Fortunately, it looks like Orkut is actively and quickly deleting them, to stop the spread. I say completely unsarcastically, good job Orkut on the quick response!
Looks like it joins you to an Orkut group, too:
Infectados pelo Vírus do Orkut.
Owner of the group is a new-looking account named "Virus do Orkut". Also, listed at the end of the virus.js file is this: author="Rodrigo Lacerda"
