Seeing that it's a Norton message, I would say that it's giving you a false positive. Norton tends to do that at times.

I'm using CA Antivirus, which I highly trust, and I haven't been receving any worm/virus/trojan messages when I come here, and I just did a virus scan earlier this evening.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
