I have had AVG and Ad-Aware for awhile now and they have worked great but yesterday I got my first pop up in months. It said on the very top of it, where the title of the page is, ad serving. Also I wanted to clean up my PC'S registry but all the registry freeware programs I tried would only clean 15 viruses out of my 144 viruses. Finally are their any great freeWARE PROGRAMS.
