I visited NBC.com just now and received the message below. I didn't click on the links that appeared after the message. (For security purpose I didn't provide the links here). I only visited the site and closed out of the page using Task Manager. I ran virus / spyware scans and nothing came up.
Should I be doing something else to make sure my computer is clean?
