how can i remove safe fighter from my computer ?
Never heard of it before a google search would tend to indicate a rogue/fake security application.
I take it that you are getting fake security alerts that your system is infected, etc. ?
If so don’t visit any sites it links to.
If you haven’t already got this software (freeware), download, install, update and run it and report the findings (it should product a log file).

SUPERantispyware On-Demand only in free version.
Don’t worry about reported tracking cookies they are a minor issue and not one of security, allow SAS to deal with them though. - See http://en.wikipedia.org/wiki/HTTP_cookie.
