Nasty Worm Spread

Now I know why I got some viruses last Tuesday and until today, my desktop computer had crashed many times because of this nasty worm spreading and infects millions of computer every day. This virus is called "Conficker" or "Downadup"; it is very strong virus we have ever seen today, so you must be careful over there! This virus infected millions of computers daily. I am having a difficult time to fix my computer back in normal after I had this nasty worm virus; my computer is always crashing even after reformatting. Indeed, this very disgusting!
