I've never heard of that either but it made me curious enough to do a LOT of searching. I ran across this:
This thing is just a hosts file hijacker.... Removing the hosts file or removing all entries containing the following IP 126.96.36.199 in your hosts file (which incidentally now resolves to a page explaining to come to TweakXP to resolve the issue...hmmmmm) will solve this isuue temporarily....
Ad_Aware and Spybot S&D do not yet remove/fix this problem.
To find the hosts file.
file name is hosts no extension. open it in notepad and delete all references to search engines OR just delete the whole host file.
If you are on Windows 98 or ME, the hosts file is located in C:\Windows\
