This is by far the best Internet Security suite i have ever used. Nice, clean UI, only the features that you need (why would you need parental control on your work laptop?), powerful AV and firewall, plus the ability to do backups to online drives! In my opinion, it stands way ahead of BitDefender and ZoneAlarm. These 2 do work most of the time, but slow your system to a degree when it becomes almost non-usable. The BitDefender services several times a day stop responding and PC requires a reboot. And i have tried many installs on several Vista and XP PCs. Norton Suite has a well designed UI and update system, but its AV is not very effective. I found malware it missed using other tools. Bottom line: I really like BullGuard and am planning to buy it after my trial period expires.
