[Inactive] addware:win32/addlyrics

I have Win 7, 64 bit, I've been getting pop up adds in my browser that just keep coming back. I went to add/remove programs to see which ones were added recently & there were two with the word Lyrics. I deleted them & ran a program "˜malicious software removal’ to search for bad stuff & it didn’t find anything. But I am still getting warnings from "˜MS security essentials alert’ saying there is something that is a potential threat. When I get it I check the details & it always says addware:win32/addlyrics. It says it's in It is in- file:c:\windows\temp\sbs_ with a bunch of numbers after that. When trying to find it in that file it isn't there, when I do a search for how to remove it it takes me to a page that is password protected. Any help would be appreciated.
