In the past 48 hours I have attempted to sign on to CitiBank website. I have been warned/blocked that it contains malicious content. Is this an error or has the site been hacked?
Please try.... clear browser cache + run Norton LiveUpdate until no updates + machine Restart (not Shut down).
Post back progress.

That took care of the problem.
