It appears that Win XP is not recognizing Avast. The Avast icon does appear in the Task Bar and if I mouse over it displays a message that Avast is running and that my system is secure. Yet, the Windows Security Alerts shield also appears, in red with an X through it. When I launch it, the Windows Security Centre indicates that my Virus Protection is OFF. To the best of my recollection, this was never the case previously. Can anyone shed some light on this.
