Orkut was hit by Bom Sabado virus, which means Good Saturday in Portuguese, on Saturday.
The virus posted scraps to the Orkut users with the text Bom Sabado and is sent to the users account by the name of the other friends account. It also added affected users to new Orkut groups.
The Google statement notified all users that the worm was cleared and Orkut is safe.
This is the second virus attack on Orkut. The attack came just after a month Orkut unveiled the new exciting home page and features.
This is to inform you all that we have contained the Bom Sabado virus and have identified the bug that allowed this and have fixed it. We are currently working on restoring the affected profiles. Thanks a ton to each of you whos made an effort to alert everyone else about this. I will make sure to keep you guys posted on more updates, said Google Inc in their blog.
