Istart wesearch & Rising virus

these 2 programs have latched on to my pc and I can't get rid of them. I ran the cleaner, I scan for errors but whenever I try to delete these programs, it asks for administrator permission. I am the administrator, no one else uses this computer. Please help!!!

rule 10, found here; http://forum.piriform.com/index.php?showannouncement=15&f=9 does not allow forum members to give advice on malware removal, which certainly would be the first thing your PC needs.

read that supplied link as it also has links to malware removal sites.
