The following hoax is very similar to the "Yahoo instant message" hoax. The hoax, which has been spread via email and instant messaging, warns instant messaging users to be wary of adding someone to their buddy list.
The text of the hoax reads as follows:
If someone by the name of Mark Genesis Gallardo (rugbylegend) wants to add you to their list, don't accept it. It's a virus. Tell everyone on your list because if somebody on your list adds them you will get it too.
It is a hard drive killer and a very horrible virus. Please pass this on to everyone on your list. We need to find out who is using this account.
Sorry for the inconvenience. Right click on your group name of your buddy list and click Send Message to all. Copy and paste
