But it does, if it's the real Avast.

From where did you download it? What is your Windows version? What was the AV in use prior to Avast?

Welcome to the forum.

I have this problem too - when Avast! 5 was first installed (Windows 7 64-bit), it was recognised by security center; however (7 weeks later) the system suddenly announced that there was no anti-virus software detected.  I have tried the repository files "fix" as suggested but this had no effect (the repository was declared to be "consistent"). This was on a new laptop which had a trial version of McAfee pre-installed, which was removed using the proper removal tool prior to installing Avast! 5.  As I said above, though, Avast! was recognised ok for the first 7 weeks.  Automatic updates to Windows and Avast! are working correctly.  

.NET framework 4.0 was the only new software installed anywhere near the time of the problem.

Avast! 5 itself appears to be working fine (as far as I can tell) - this seems to be a false report for some reason.  Could a recent windows update or Avast! update be responsible?  I see that Windows Update is now showing Microsoft's own "Security Essentials" package as a recommended update, is this coincidence?
