After upgrade, my antivirus wouldn't start. support adviced me to uninstall One care and install trial version. When I tried to install I got an error message 0017-8004023C. I have Xp 2 version of windows. Help! I just looked at my system info and see a one care file that says damaged.{13EC55CF-D993-475B-9ACA-F4A384957956} Could this be the problem? If so how do i fix?
