I just purchased and downloaded Kasperskys yesterday for my Dell Laptop (Vista) and thought I uninstalled Avira Antivir Personal Edition but it still shows up as being active when I go into the Windows Security Center? Say's that multiple antivirus programs are running? I've tried everyting to get rid of Avira and am at a loss? My computer is running fine but I would rather not have Avira on it. Can anyone help me?
