Security Center in Vista Doesn't recognize Avast

[ecoplnd]

Just installed Avast on HP Laptop running Vista 32.  Has been updated to Service Pack 2.  I had AVG Free which ran fine until Service Pack 2 was installed. Vista Security Center notified me it wasn't running, even though it was.  I uninstalled AVG and all of it's settings.  I then downloaded Avast Home and had the same problem.  I ran from the command prompt, as administrator, verify repository and got a good response.  Also ran stop net winmgmt, renamed the repository folder and then start net winmgmt, rebooted.  Now Security Center doesn't even see Avast as my AV.  I know I can tell Security Center that I will monitor AV myself.  Is this program not compatible with the latest version of Vista?  Avast is definitely running so I am not too concerned. I just like things to run properly.

Thanks.

Well... what we suggest seems you've already done...
I suggest you follow (again) the instructions here: http://forum.avast.com/index.php?topic=23457.msg193534#msg193534
Check your system time and date also.
