Need Help !Win7 can't start

I'm not good at English.

I get a virus on cell phone.And Norton warning when it combines computer by USB.

Then norton tells me it needs to be restart,I click yes.

And the process of starting win7 stop at that 4 things with diffrent color get together.

That is still change,light or dark.But I wait 30 minutes it doesn't go ahead.

I restart many times ,it's same.

Now I'm using Fedora16 to make this message,what should I do?
