Hi,

You might like to look at:

http://www.webattack.com/get/hostadmin.html This is an "easy" Windows "Hosts" management tool.

Also when using SpyBot S&D take the "Immunise" option to prevent the stuff getting on your machine in the first place.

lumpyporridge has pointed you to Lavasoft who do "Ad-Aware" 6.0. This is another product that complements SpyBot. WARNING if you use SpyBots advanced options to block browser hi-jacking and changes to IE from within IE (changes have to be made via Control Panel) Ad-Aware will report two entries as malware. They aren't, they are these two security features in SpyBot

Also with the Hosts Administrator, some defence mechanisms will register stuff in here (Spyware Guard/Spyware Blaster?) These entries point to 127.0.0.1 which is an internal loop. This is quite safe and intentional so don't remove them; the entries effectively block the malware from "phoning home"

Hope that this helps...........Good Luck!
