I have home search assistant, shopping wizard, etc. installed on puter-I need help

Somehow, home search assistant was installed on my computer when it was on but not in use. Now each day something new is installed. Now shopping wizard installed it's self and these programs are installing porn and other programs in my favorites folder. I try deleting them, but they keep coming back. There is nothing in my add/remove programs that shouldn't be there except for the search assistant and shopping wizard. I need help! My puter is running slow and most of the time it doesn't respond to anything. HELP ME!!!
