First impressions.
I was very impressed with the way BitDefender is presented to the user. The website is cleanly designed, the download link is clearly visible, there is no data to fill in before downloading and even after that, you can delay the trial version's activation process if you are only evaluating.
The installation process is fast and simple. It does not install any unwanted software, the only complaint being the nag screen it shows at login until you buy the program. However, there is nothing intrusive and if it were not for the icon in the system tray, you wouldn't even know there's an antivirus installed.
