I bought a Media Computer from Tesco a few months ago. It had MSN Mesenger 4.7 pre installed. I was invited to install MSN Mess Vers 7.5 so to communcate with voice & web cam. I cannot find Vers 4.7 on the hard disk to delete it. I have 2 versions running all the time and slowing down my PC. I have 2 icons and never know which one to clik on. Can you clever guys and girls help me to delete Vers 4.7. Thanks!!
