How to Remove Search.offersbar.com Browser Hijacker Effectively and Safely

My homepage is attacked by Search.offersbar.com. I tried out removal directions in the forum, but it is still the same. Whenever I open a web, it always goes to Search.offersbar.com at the end. It makes me crazy. How to remove it completely? Can anyone tell me?
