Avast not being read

well i had avast for sometime now and its always been working great. i have avast up and running right now but today windows security center isn’t detecting it and it says no virus protection. i have home edition and its already upgraded to 4.8. i have vista home premium and i dont know if its a windows error maybe a virus. im not actually sure. soo can anyone help me out?

What version if windows ?

The WSC is flaky at times, so the important thing it to ensure that avast is running.

  • What avast processes are running in Task Manager, they begin with ash or asw, see image ?

Sometimes, Windows Security Center stop recognizing your antivirus or firewall… So, check your system time and date and also http://forum.avast.com/index.php?topic=23457.msg193534#msg193534
