Here is a good article on browser hijacking. I am by no means an expert, just another victim that had to learn the hard way.

That's a good article. I had to clean up two messed up computers in the last two weeks, and I basically followed a similar routine.

One thing to check is to make sure your "hosts" file isn't filled up with entries. The hosts file is a text file located in C:\windows\system32\drivers\etc. The "windows" directory might be "winnt" depending on the operating system. The only entry that should be in a default hosts file is "localhost 127.0.0.1". Any other entries are suspect, especially if they point to the 127.0.0.1 address and are for URLs such as Windows Update or Antivirus software vendors.

There is a block of text with examples in the file, but it will have #s in front of each line, rendering them harmless.
