Is there any one know what happen to my msn.. its version 7. The problem is whenever i log on to msn, it will automatic send a number of files to those who r online. And once they accept, their consequences will be like mine. There are total 9 of this MS.DOC files stucked in my C drive, no matter how i tried to delete. it will still return back. Is tis kind of virus. The neligence of my brother to accept this file from his fren, as his fren also got this problem too, this goes the same to my friends who have accepted the file i sent.? Can any how??

I think you've got infected with a virus. Get an antivirus software and scan your computer

If you want an online scanner, I personally recommend TrendMicro's HouseCall.

infact, im pretty sure shes been infected with that worm thats going around, well that what it sounds like anyway, dont you need to get the uninstaller of it (sorry i dont have a link)
