Because of virus infection I had to format/reformat/update and lost the functionality of IE, Firefox and WMP. I've read all advices and tried to apply as long as conformity but nothing solved the problems: IE cannot open web page and WMP doesn't work in any way. What intresting are windows cannot find any problems with my network&internet connection, besides Opera, Avant, Aol, Netscape can serve. I'll appreciate all helps. Note: Vista Home Premium 32 bit.
