i clicked two of those links now and nothing came up so i'm wondering if i have it. i'm not sure since on other websites it says it ask you to download stuff.

Sometimes they take their time before they actually execute anything. You may have gotten extremely lucky and nothing happened.

The links you're referring to are almost always malicious links. Don't trust them enough to click on them.

Koobface, an anagram of Facebook, is a computer worm that targets the Microsoft Windows users of the social networking websites Facebook, MySpace,[1] hi5, Bebo, Friendster and Twitter[2]. Koobface ultimately attempts, upon successful infection, to gather sensitive information from the victims such as credit card numbers. It was first detected in December 2008 and a more potent version appeared in March 2009.[3]

Koobface spreads by delivering Facebook messages to people who are 'friends' of a Facebook user whose computer has already been infected. Upon receipt, the message directs the recipients to a third-party website, where they are prompted to download what is purported to be an update of the Adobe Flash player. If they download and execute the file, Koobface is able to infect their system. It can then commandeer the computer's search engine use and direct it to contaminated websites. There can also be links to the third-party website on the Facebook wall of the friend the message came from sometimes having comments like LOL or YOUTUBE. If the link is opened the trojan virus will infect the computer and the PC will become a Zombie or Host Computer.

Among the components downloaded by Koobface are a DNS filter program that blocks access to well known security websites and a proxy tool that enables the attackers to abuse the infected PC.
