F-Secure adds rootkit detection

This is obviously a good thing. Rootkits have existed for quite a while in the *nix world but to my knowledge have not gotten a lot of publicity in the Windows world until fairly recently but are apparently becoming much more prevalent. I first became aware of rootkits while reading "Exploiting Software" by Greg Hoglund and Gary McGraw, an excellent book for anyone interested in the geeky details of this. (Be concerned, be very concerned.) The scary thing about rootkits is how stealthy they can be, as well as the damage they can do. I imagine that most of the antivirus/anti-spyware companies will be looking into rootkit detection soon. One more example of the "bad guys" becoming ever better at what they do and the "good guys" forever playing catch-up.
