There’s another bit of malware spreading through MSN’s messaging network (MSN Messenger and Live Messenger), known as the IRCBOT-RB Trojan, also called a worm because of how it spreads.
It works by showing people a message with links to pictures on MySpace and Facebook. It includes messages such as "Wanna see my pictures before i send em to facebook?". Clicking on the link takes the user to a web page with malicious code.
This particular worm/trojan changes the message into different languages, depending where the user is located.
Once infected a user’s machine waits for instructions from the malware author and will let them control the machine at will.
