Friday the 13th. I figure the hackers are operating. I am unable to log in (using Internet Explorer 7) to broker websites this morning. I can view other websites such as news.google.com and elitetrader.com normally. Using Mozilla Firefox (version 2) I am able to login to some broker websites. Norton Antivirus also shows 5 errors that it can not fix. I vaguely remember the Norton Antivirus problem first appearing about three days ago then disappearing.
