I cannot get any anti-virus to work on my XP-fired dual-core. Every one I try to install says there is AV already running. Search shows under “C\profiles\common files\authentium\anti virus; it is not in add/remove list; it is read only and 36MB; what is it? More importantly, how do I get rid of it? If not that, how do I turn it off? No AV runs well or updates with it running. Help…..MikeP
