My OS is Windows XP Professional. The types of things that are coming up are in the security center as red warnings mostly. They now say that 'realtime scanning is disabled, detection file signature is more than 30 days old, spyware, potentially unwanted programming scanning disabled, IM and scrip scanning are disabled and buffer overflow scanning disabled'. Before, it was more or less, only saying that my detection file signatures were more than 30 days old. It would try to update, and it just wouldn't install it. It would say it was installing 'McAfee Virus Scan', but it wouldn't do it. Also, how do I find what version I have? I go to the 'about' section, and it gives me Security Center 8.1, VirusScan 12.1, and Personal Firewall 9.1. I have reinstalled McAfee from the Comcast website several times, but this fixes nothing.
