DON'T CLICK ON YES TO DOWNLOAD THE "SPYWARE REMOVER"!!! 
 
I suspect that your PC has been infected with malware designed to sell a malware removal product or else to load some other nasty software on your system.  
 
If you have not done so, please install and run a complete scan using your antivirus software. Then run a spyware/malware removal product. (Spybot Search & Destroy is available for free or Ad-aware has a crippled, but free version.)
