I have Bit Defender Internet Security 2009 installed (just 2 weeks ago). This has been running daily and showing no infections and on average deleting 2 cookies from my system. Because I was surprised that there were only two cookies being removed I reinstalled CCleaner, which I had used successfully for years. This program removed dozens of cookies from weeks ago. I also ran the registry fixer which comes with CC and this removed 293 items. Should BD be deleting more temporary files than it is and does it also review the registry and fix problems there?? The other question I have is on startup I have an entry called BD agent. Is this to do with BitDefender and what is it? There is another startup entry called BitDefender Antiphishing Helper - is this required at startup?
