Website "Annoying"

I was notified today by Sucuri that my website, safecandc.com, has been blacklisted by Norton. I assume this is due to a malware infection that occurred a while back that has since been cleaned (and my site is now protected by Sucuri). I signed up on the Norton Safe Web site in order to try to clear things up and get my site listed as safe again. However, I am having trouble. I've added the meta tag in order to verify ownership, but I keep getting a message that "it cannot be verified". Without this verification, I cannot ask for the site to be reevaluated.
