As of today, when I try to check on the History or Quarantine, the related screen pops-up for a split secnd and disappears. It does not give me a chance to clear history. The “View Network Security” section works fine. I have NIS09. I am on the 60 trial that I got when I got my computer. I’m running Vista Home Premium SP1. the history/quarantine was working fine until today. I’m 23 days into the trial, so it has been working fine up until now. Any help is appreciated.
