Hello. I have a problem with the Windows Security Center.I am using Win XP Pro with Service Pack 2, and Anti-Vir Personal virus software. Everything was fine until two days ago, when the little alert balloon told me i have NO anti-virus software installed. Security Center USED to recognize Anti-Vir Personal, even warned me when to update it. But for some strange reason, it fails to recognize i have ant-virus installed. Any ideas?
