This one is pretty easy to fix. Just go to the website, find the help/faq button and select it. there is a link to a removal tool.
When the toolis run it will ask if you want to force delete the prog, select yes and it goes away.
The hijack probably came from an update to the msn mesenger program. Its very trickily worded so that you install my searchnow.
A search on google will show that its a common problem.
