Hi aarhus2004,
Yes, the projections for rootkits are that by 2008 roughly 80+% of infections will occur by way of rootkits.
F-Secure is but one tool, and we should all use several. I also use RootkitRevealer from Sysinternals.com and Rootkit Hook Analyzer from Resplendence.com.
Here is the latest English version (not the help file) of IceSword recently made available:
IceSwordv1.18en:
http://rapidshare.de/files/21011497/...1.18en.7z.html
Its touted for advanced users, and can detect and remove Hacker Defender rootkit - but the author of Hacker Defender, Holy Father - now is in the game for more than fun, i.e. profit, and he and the author of IcsSword are both trying to outwit the other.
Process Guard (paid) is probably the tool of choice to defend against kernel rootkits - I'm running the free version now, but plan to switch over sometime in the future when I can migrate my firewall (to Jetico) after my AV license is up, and I decide on NOD32 or Kaspersky AV, and I finally get a DSL line and install a hardware firewalled router with NAT and SPI.
Also, SocketShield looks like a winner - now in Beta test with version 0.96 - its already stopped serveral attacks from meta file and iframers launcher scripts exploits.
I also run Firefox 1.5.0.3 with the NoScript extension although Java and JavaScript are turned on - this blocks the JavaScripts from running by default, and I have to allow them on a temporary basis - I even block the Google syndication and google-analytics from TSG and use the CustomizeGoogle extension with Privacy checking to block Google from gathering a file on my Internet use. Also, running SpoofStick extension to Firefox.
