As trjam states there are many features included in F-Secure, especially Internet Security. What I believe the company have recognised is the importance of protection at every level within the system, so we naturally see new features as the product develops. They were the first vendor to tackle the complexity of rootkit detection and release a solution (backlight engine)! What isn't obvious, nor available through the installer, is that you can actually uninstall unwanted features via the command line, such as Parental Control - thus reducing the load. The Trend screenshot does only show the processes of their anti-virus/anti-spyware product rather than their heavier firewall product. When you think about it, the firewall is one of the hardest working processes on an interconnected system. This will only increase with network bandwith. Don't believe what Windows process explorer is telling you, it's just a Windows API call to hide a process from view! While speaking about firewalls, I usually recommend to most home users that they have a desktop firewall product; most state they have one on their router, but ask them: 1) Is your router/firewall packet, stateful or application layer? 2) Would it scan outgoing connections? If you really wanted a comparision between just AV products then try the still supported corporate F-Secure Anti-Virus for workstations. It's very fast and supports older and much slower hardware. With this said what has worried me with F-Secure home user products is the lack of granularity with some of it's features. I don't know what granularity the recent FSIS2008 product has, but I remember in the 2006 version 3rd party cookies were either on or off. It needed the ability to be on with a user defined exception list for URL's. Just because the cookie doesn't originate from the current domain doesn't necessarily mean it's potentially an issue.
