I have a computer virus. Can someone help me out?

I think I have a computer virus. I have SBC Yahoo DSL internet, and I have all the antivirus and online protection downloads. I use both often. My internet is slow, freezes up and I get pop ups ALOT. The anti virus software pops up telling me my computer is infected, but doesn't give me the option of deleting them. I don't want to have to completely restore the computer. Is there a software or something I can download that will get rid of the viruses and make my internet fast with no popups again?
