It is not always about it being an attack by a virus actually. The most common reason for the attack is spamming and to try to take control of your system and turn it into a zombie unit for them to use it to spam other people or as a series of nodes to hide their attacking some system they have in mind for hacking. They do this to cover their tracks and sometime zombie PC owners gets into trouble becasue of this.
The most common attack is taking advantage of human nature. In this case, it is some "girl" request that you add them or ask you to add them. Once you do so, it can take advantage of certain weak spot in maybe your version of MSN or they will give you links that will send you to websites that once you are viewing the site's info... you already got infected. These days....virus,spam or spyware does not always use email to trick you to click open an attachment or use HTML scripts. A website itself is a HTML, flash..etc. All these are a series of action script that produced certain effects or play music and play a flash animation the minute you get into the site. Problem is, some of those action also have dangerous stuff that get trigger the moment you are in the site. So becareful..never add people that page you to add them. We are not that desparate to know another girl are we????? heheheh... Okay maybe some do...then I say...good luck. Hope it is really a girl and not malware script in Girl Skin heheheheh...
