Where did you get X-Clean program from? I saw one program by that name that is used on Macs for cleaning, not antispyware.
Check your add/remove program and addons in IE for "Gonna Search". I suspect you want find anything.
You can also scan with this top of the line programs--Super Antispyware and Bit Defender
Install Super Antispyware. Run it in safe mode. Allow it to quarantine whatever it finds. http://www.superantispyware.com/
Run the online scan for Bit Defender in normal mode. Allow it to quarantine whatever it finds.http://www.bitdefender.com/scan8/ie.html
