How did a Facebook folder and Icon get on my desktop?

[Sundrop]

I have a Facebook folder filled with a whole bunch of Java scripts, photos of my friends, and things I've looked at , as well as a bunch of advertisement photos of things like Jamba Juice, and Olive Garden on my desktop. The contents of the folder are 2.59 MB (2,721,677 bytes). Right next to the folder is an IE (Internet Explorer) page icon for Facebook. I have never explicitly downloaded anything from Facebook onto my desktop, so I do not know how this folder could have gotten there. It says it was created last year, and I have had this computer for about four years (and have been using Facebook for about six or seven years). I honestly did not create this folder.

I use Google Chrome, and I have been using it for the past three or four years. I just find this weird. I have never heard of an internet site that a person frequently uses downloading Java scripts onto their desktop in a folder unless they had to download a program to use the site (like a gaming site for example). What's even more weird is that I cannot find anything on Google that addresses this issue.

Happy for anyone's input.

There is virus that appears in chats ( its zip file that u can download it ) ,when u chat with friends, or it shows that its been sent by your friends to you , so if you downloaded it make sure u will scan your PC with good antivirus , coz that file is virus that spreads via facebook.

Or you maybe saved the facebook page to your PC as HTML
