I wonder whether someone could help me.

I have Norton Internet Security installed on my laptop. I was looking at a
site this afternoon, when a message popped up from Norton, saying there were
new updates to install, so I chose to install them. Once it had finished,
the message popped up, saying I would need to restart my computer, to which
I clicked OK. So, my laptop rebooted.

I was still looking at the site when I chose to reboot, and since then I
have experienced problems accessing that site. I managed to access it
straight after the reboot, but it was slow, and then since then I just keep
getting an error message. Could it just be coincidence? All other sites I
use work fine.
