I have lost my home page!!!!!?

I am currently running my P.C. on windows XP. I got a load of Viruses/Spyware in my computer and used Antispyware to take care of the problem. The trouble i am having is that when i try to get my Yahoo home page i keep getting a warning hat directs me to a page that is forcing me to buy a program called Malware/Antivermin which I dont want/ need. Any one that can tell me how to get rid of the annoying page and back home will have a friend for life thanks to all who took the time to read and answer this Q.
