download MS anti spywayre. it's free and you don't have to deal with cracked programs. Also, get it off you machine, Now!
Then something you should have learned... Downloading will in the end result in spyware... but it's your call..
anyway, the free tools out there are just as good, so don't bother with the pay ones...
If you cany use MS anti spy, then use spybot search and destroy. It's prett good to. Also, do you have antivirus? if not, you need to get AVG free, and get cleaned...
Good luck to you.
