Virus Protection not found

Avast version pro version 4.8 1335  with a problem that been reported before, I am using vista ultimate. I have tried all the post advice with stopping WMi deleting the folder from wbem, restarting etc. but nothing seem to help. Do anyone know what could be the problem, thanks for any help

Just stop avast! and start it again (via icon next to Windows clock). That should fix the problem.

Thanks, did as you said but still saying the same, so I stop it and restarted the pc and still not found

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

Followed all instructions but still nothing changed, thanks for all help

So (from your last reply) you stopped the appropriate services before deleting the repository, then promptly rebooted? Those services set to automatic?
Any other AV been used on this computer?

[ronnycopeh]

None on this pc, always used avast. I finally got it straight, I had to use system restore to go back to a earlier time when it did show, so thanks for all the help, you guys are the best and always respond timely.

Stopping avast! works for me. This problem with Security Center started after Microsoft changed the way how Security Center detects security applications some time ago. At least from what vlk said, it's designed really awful and we couldn't find the actual cause why this happens.
Anyway, good to see you solved the problem.

It won't hurt if you try to repair your installation:
Go to Control Panel > Add/Remove programs > avast! antivirus > Remove. Then choose Repair function in the popup window (Repair).
