Just remember one thing. Gator and especially Comet Cursor are "Spyware" and they don't want to be removed. They want you to go to a web site to fill out a survey as to why you want to remove them. 
You may want to run Ad-aware after your attempt to remove Gator. You can find it at - http://www.lavasoftusa.com/
