You need to download Super Antispyware to another medium (CD, flash drive) using another computer then install on the infected computer.
Install Super Antispyware. Allow it to quarantine whatever it finds. http://www.superantispyware.com/
Let us know the results of the scan. Also, give us the link to the instructions that you found on this site to remove the malware you have.
