I keep getting a "High Risk Website Blocked' - Sophos message on my screen on all browsers. How can I remove it?

The issue was resolved with Google. I no longer have a virus issue. Everything has been cleaned. But I keep getting the message when I try to go to my site:  http://marksudell.com/

I cleared the cache and even removed Sophos... but it keeps showing up on my computer only.

Any idea how I can remove it??
