Everytime I scan with the Microsoft Spyware Beta version it wants to change my home page on Internet Explorer 6 to leopardsearch.com. After it cleans in reloads itself whether I reboot or not. Spybot, Adaware SE 6, Advanced System Optimizer, System Mechanic 4, SpySweeper 4 and SpyEliminator 4 and none of these detect it. How can I fix this problem? Thanks
