On a PC running XP Pro, it seems that after the update to 2.03 from 2.02 the website protection stopped working (starts momentarily then stops and cannot get it to stay on). However, this is the only PC out of three running XP that has this problem. I had read several threads on the problem of website protection failure and ran the various tools to try to detect and fix potential problems, but nothing worked. I was going to do a clean install of XP but decided to hold off on it. Instead I accidentally reinstalled 2.02 and noticed that website protection starts and stays on. So I will stay on 2.02 for now.
