I am having this issue. It was being detected perfectly well, but today this has stopped. I am using Home withXP Home. I have tried uninstalling and then re-installing but with no success. I know that I can manage the a/v myself, but I like the reassurance givenby knwing that XPis doingthis, too. Also, I want to be advised if definitions etc. are not up to date. This topic has been viewed many times, but there is no answer as to how this can be fixed. Any help gratefully received.
